USB ports randomly stopped working on Windows 7

Q: USB ports randomly stopped working on Windows 7

So my USB ports decided to stop working. I'm using Windows 7 and they were working fine this morning until I unplugged my USB devices and packed my computer, then when I came home, the ports stopped working. I have two ports and I've tried placing three different items (two mice and 1 webcam) in all the ports, no avail. Even the light under my mouse isn't lighting up. I restarted twice and when I go to device manager there are no exclamation marks or anything wrong under USB tab.

I even uninstalled all my USb serial controllers and restarted and they got installed back but still nothing. Then I disabled selective suspend and nothing too. =[
Any help guys? thanks!

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/directdownload.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I've noticed that nobody's replied to your post, so I figured I'd try to say at least a little something. I'm not too sure that it'd be of any help to you, but have you checked any settings in your BIOS that might be responsible for the control of it? It's probably a bit of a long shot but it can't hurt to check it out.

I am using Windows 8.1 on an ASUS X550C. All my USB ports (2 USB2.0 and 1 3.0) have suddenly stopped working. External drives when connected show a light but are not recognised. Graphics tablet and printers also do not work, though they do when attached
to another printer.
I have not recently done anything by way of software installations.
I have done a clean boot, but no difference. I have ensured the latest Windows Updates are installed.
In Other Devices, the USB Root HUB (xHCl) has a yellow exclamation mark next to it. Searching for an updated driver produces no result.
Everything else on the machine seems to be working ok.
Advice please.

Hi,
In the Intel download center, we can only find the driver for Windows 7
https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProdId=3467
And the link below mentioned that Windows 8* has a native in-box USB 3.0 driver.

http://www.intel.com/support/chipsets/usb3/sb/CS-033977.htm
Windows 8* has a native in-box USB 3.0 driver.
since we're unable to to install the driver via Windows update or download it from manufacture website, but the driver must be corrupted in your system for some unknown reason, so I suggest you return the system to a previous point at which everything is
function fine with restore point.

Post upgrading to Windows 8.1 Pro on a Dell XPS15, 'only' 1 of the 3 USB ports has stopped working. The other 2 are working fine. I have the latest BIOS A16.

I've uninstalled all USB drivers and had them auto-resintall on boot. No change, 1 USB port (the one with powershare) is still not working.

I'm not getting much on the Dell forums for this. Any ideas how to fix.

A:1 of 3 USB Ports Stopped Working Post Windows 8.1 Upgrade

Did you check the power options? USB Selective suspend could be the problem

Windows Key + X > Control Panel > Power Options > Change Plan Settings > Change Advanced Settings > USB settings > toggle the 'USB Selective suspend' setting to enabled if it is disabled, or disabled if it is enabled. Apply and reboot. If it doesn't work upon reboot, toggle it one more time and reboot again.

My graphics card is ati radeon 3450. i know its older but thats fine for me. money is tight so if so i want to avoid buying anything. im using Windows 7 x64. The MSFixit for Aero says that my graphics card does not support Aero. I know is false because its been working fine. I have directx 11 installed currently. I am all the way up to date on Windows updates. I have downloaded the latest driver for my card from ati's website. tried uninstalling and reinstalling it. Looked at my system restore points it shows nothing happened within a few days of my problem starting. im not sure what other info to give...thanks for your help!

Unplug ALL USB devices.
Open Device Manager.

Uninstall all devices under USB Controllers.
Uninstall all devices under Disk Drives that you know are not present.
Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.

NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function. I don't have one yet, so I haven't had time to modify the instructions.

A:Usb Ports Stopped Working

I can't say for sure, but if you've reinstalled the OS and still can't use the USB ports - then it's time for a repair/replacement. It sounds to me as if it's a partial failure of the USB ports (the data channel rather than the power) - but I don't know a whole lot about their construction. Sorta like one of the traces that the data travels is broken, and it's broken before the split to the different ports (but this is only speculation on my part).

I may have seen the same thing at work not long ago - but can't recall the make of the system. As I seem to remember, we shipped it off for repair at the service center.

Look in your device manager and see if any USB devices have show to be not working or not installed. In any case try deleteing the USB Controller and letting Windows reinstall it.

hi all, this problem started out as just one port, but quickly has spread to all ports. i installed a new printer hewlett packard 3550 deskjet, which initially worked perfectly and then died after printing once. i have also just installed a dvd burner (LG super multi RW) which doesn't seem to work properly either. since installing these new things all my usb ports have died. further i have to restart my computer often three times before the mouse will work. worried. any suggestions?
 

A:all my usb ports stopped working!

uninstall the new stuff and restart with the printer connected.
this should reinstall that device and it should work more than once.
Once that is stable, repeat with the dvd.

using the device manager, you should never see a red or yellow icon, which
says disabled or problem respectively

one of the usb devices attached to this computer has malfunctioned, and windows does not recognize it. for assistance in solving this problem, click this message

clicking the message brings us a screen that shows the 3 available usb ports, with an unknown device in one of them. at the bottom it says a recommendation to try reconnecting it and if windows still doesnt recognize it, replace the device.

this device has always worked without any problems for the 3 months ive owned this computer and so has the headset so im pretty convinced the devices arent the problem.


Have you updated drivers or downloaded any programs in the last 2-3 days?

Can you see them in your device manager? computer>system properties>device manager (left)>Universial serial bus controllers (usb)
Any yellow triangles?

A system restore would more than likely fix it if your really stuck.

A:USB ports stopped working

Borrow or purchase a ps2 kb. Enter BIOS and enable USB KB/Mouse. I'm not sure it is called exactly that, but it is something similar that you will be able to find. I too have a Gigabyte motherboard (older than yours even) and have had problems with it liking USB kb inputs until I explicitly set that in the BIOS. What is weird is sometimes USB will work if that isn't set, or sometimes it will half-*** work, as in I could get into the BIOS or force the boot selection menu, but then the kb wouldn't work.

So bottom line is, I know what you are describing, but I don't know of a good fix, outside of just acquiring a ps2 kb which will get you out of this situation 100% of the time.

I am new here and not sure if this post belongs here, if not please point me in the right direction.  
About five month ago I built a pretty basic computer. I have been using a pretty crappy tower since then and today upgraded. I switched out all the internals and set everything up in the new tower. After booting up into windows (8.1) anything connected to any USB port would become unresponsive. Although every minute or so the number lock light would flash signifying the keyboard was receiving power for a split second. I shut down the computer and booted into BIOS and the keyboard worked perfectly. I also checked to make sure the USB ports were enabled in one of the BIOS pages. Even after this the keyboard and mouse refused to work after entering windows.

Hi

I am running Windows XP SP3 on a HP Compaq NX6325.

A month ago I got all 3 of my USB ports stopped working. Device Manager shows each USB Host Controller and the corresponding USB Root Hub as working correctly.

I can uninstall the USB Root Hubs, but the 3 Host Controllers will not allow me to interact at all, i.e. I when I try to update the driver, disable it or delete it then the window freezes until I stop the process.

I have updated the BIOS to the latest from the HP website and made sure that USB is enabled.

Searching the web I have tried a few driver check programs, all of which says nothing about upgrading the USB.

One thing to mention.... from the MS website it states that USB usualy uses IRQ 9 whereas my USB Controllers are on IRQ 19.

Any help gratefully received

A:3 x USB Ports Stopped working

You cannot update...USB controller drivers, those are installed by Windows. If they are damaged, updating won't necessarily overcome that.

Go to Device Manager...ignore the hubs, uninstall each controller...reboot.

Go to the HP Support/Download Drivers page and type in your make and model. Download the Chipset driver for your computer. Install that. If still having problems, go to Device Manager and uninstall everything under Universal Serial Bus Controllers. Restart. But now go into the Bios, here see if there is anything for USB or Legacy control. Disable this. Now restart the computer. You should have nothing listed for USB in the Device Manager. Now reboot, go back to the Bios and enable USB. Restart and the computer will reload all USB devices. If this still fails, the motherboard USB chipset has failed, and you will need a new Mobo.

This morning ALL of my USB ports stopped working. If I plug something into them I get an error message saying "One of the USB devices attached to this computer has fmalfunctioned, and Windows does not recognize it." I have gone into device manager and now exclaimation points or anything. When nothing is plugged in the Root hubs show working correctly. When I plug something in and check it I see Unknown Device- then click properties and get "No drivers are installed for this device"

Why would my drivers disappear. I have tried my wireless mouse, my printer and my iPod. nothings works. I did a system restore, that didn't help.

Hope someone can help!

Hello guys!
This error happens suddenly... All the USB devices and the ports are working, they are activated on the bios, but they don't work when the Windows starts... In the Device Manager it shows an exclamation on USB controllers an says about code 10...

If I remove all the devices and then "Check for new Hardware", windows recognize all of them and everything works fine... Bu is just restart the pc and the error returns...

I've already updated the BIOS from Motherboard (updated it from USB, worked 100%), but when entering in Windows.

I've tryied to look for some Drivers, but didn't find nothing about USB drivers for my MB and Windows is using the "generic" USB Controllers...

IThe MB is a Gigabyte GA-MA69VM-S2 (which is supported by Win7) and I'm using Windows 7 x64

Thanks guys

On my Hewlett-Packard 110-412na machine running Windows 8.1, the USB ports stopped working a couple of times recently

Since USB is the only interface between keyboard and rodent, and I waited 20 minutes or so, I had to switch the machine off and back on again.

I looked in Device Manager where everything looked ok (no yellow flags). The properties of all the devices stated that they are all working properly.

On the second occasion I was writing in Notebook, which doesn't have automatic saving, and lost a lot of work.

What might have been the cause of the USB shutting down?

Bad or missing driver. You can use Speccy from piriform.com to see what it shows.

I was working normally, playing a game, but then suddenly the sound stopped working. I identified that it was the USB ports, not the speakers, that were not working. The computer has 12 USB ports, all of them have stopped working. Is there any way this can be fixed? I ran the TSG SysInfo, but it just came up with this:

Tech Support Guy System Info Utility version 1.0.0.1

I'm guessing it shouldn't do that. Please help me as soon as possible! Oh, sorry if this was posted in the wrong section!

Hey guys,

Earlier today my computer just stopped recognising my network adapter. Luckily, I've got a built-in one but it isn't any good because I only get about 25% of the actual speed I'm meant to. I've tried the following to fix it:
Restarting
Unplugging the power cable for 5 mins
Reinstalling it with device manager
Using the disc
Using a different USB port
Replacing the adapter

My computer is the Packard Bell iXtreme M5850. Can anyone help me try to fix this?

Might be worth noting that my peripherals all work in whichever slot I put them in. It seems that only the Netgear product seems to have stopped working. It is the Netgear WNA3100.

My front and rear USB 3 ports stopped working. The rear USB 2 ports still work. When I plug an external HDD into the front USB 3 ports it powers up the drive, but it isn't recognized in Windows Explorer. My USB card reader doesn't light up. Device Manager doesn't show any USB 3 devices, and nothing is showing a yellow x in Device Manager.

Any ideas? The last time I used the front ports was a few weeks ago at most. There have been Windows 10 updates since then, but I don't know specifically when they stopped working.

My computer crashed after doing a backup and the keyboard stopped working so I decided to remove all USBs and reinsert them then all my other USBs stopped working how do I fix this ?

And I get error 28 for all my USB drivers

A:USB ports stopped working

Sometimes this is a BIOS issue.
Reboot your computer and hit the "Delete" button, during "post".
It should be a black screen with white alpha numerics. At the bottom of the screen it may tell you to hit a different key, like F2.
In the BIOS,check your usb setting, in case it has gone haywire.

Also update the info in the "My System Specs". More information makes it easier to trouble shoot.

Hi guys, after a bit of help because all of my USB ports on my FS Amilo laptop have stopped working after i installed win7.

Immediately after the installation they were ok, but since then they've all stopped working. Any device that is plugged in (Webcam, mouse, USB stick, regular camera) doesn't work, windows simply says 'the device is not recognized'. The error code is 43.

I've tried updating all the drivers, both through windows update and through the manufacturers' websites, but haven't found any updates, and i'm finding it hard to believe it can be the drivers if everything was running smoothly before.

All help would be much appreciated, cheers!

Hi,
I am in a spot of bother since I have to give an important presentation and all of a sudden my USB ports (3) in HP pavillion dv6(running windows 7 64 bit) stopped working. I plugged my friend's ipod touch to charge from the computer and it did not work and after that none of the ports will work. I tried reinstalling the drivers, restarted the computer multiple times and even ran a virus scan but its of no use. Out of the 3 ports only one says "windows detected a problem with the device", the other 2 wont even say anything. I even checked at the registry keys to see if the USB ports are enabled and they were fine. My warranty expired this December so now I have to pay HP for any trouble shooting.
Is there any simple fix to this solution which I am missing?
Thanks a lot for your time!

Two possibility come to mind there may be more of course.

1. A USB port has become physically damaged
2. The port may be OK mechanically and the device damaged the electronics

Clicking this message inevitably didnt help.

This has only happened today, and I only noticed it after installing Daemon Tools v4.0 which I have now uninstalled which hasnt solved the problem. This could of course be a coincidence.

That day suddenly my PC's USB ports stopped working. I tried all USB ports with deferent kinds of drives(pendirve, mobile, modem) but computer is not responding. I tried reinstalling my windows 7 but remains same. I also tried Ubuntu, Mint, Hirens Boot CD etc but no OS finds my any kind of USB disc. On windows 7 I tried uninstalling and installing USB drives manually but don't work. In the mean time today at dawn one of my USB modem started working(on Win7) but after some seconds it became like before.

Can anyone figure out which problem I'm facing? Is it related to my hardware?

A:Suddenly all USB ports stopped working on win 7

First place I would start would be update all primary drivers for your PC, what ever flavor you have, desktop/laptop. Go to that vendors website and download and install all the latest drivers. If you have add on specific hardware go to that vendors site for drivers.

The next thing I would do is to rule out any Virus's, malware, spyware and adware that my be lurking about your system. It's known that some of these nasties can and do corrupt system software and hardware.

Recently both my USB drives stopped working, once in awhile right after I restart they will work fine, and then randomly stop working again. It's completely baffling! lol I have looked in Device Manager, and it says that everything to do with USB is working properly, and it also says that it can detect my mouse and that the mouse is working properly. I have looked through other threads on here to see if I can find a solution but nothing seems to be working. I'd appreciate any advice, or just to let me know whether this may be something to do with an actual part and not just computer settings. Thanks

Any thoughts? Thanks for any help.

Please plug in the digital camera and the MP3 player.
Then check Device Manager to see what it has to say about the 2 devices.
To get to Device Manager, go to Start and type in "devmgmt.msc" (without the quotes) and press Enter.

Let us know if the devices are detected.
Let us know if they have any problems (red x's or yellow !'s)
Let us know if there are any unknown devices.

Everything was operating correctly yesterday, but when I booted up my computer today my wireless mouse refused to work. After trying a fix involving a USB stick, I realized that none of my USB ports work. The ports light up when I restart, until Windows 7 finishes logging in, and once it begins the drivers refuse to work. Is it because of the recent updates? Because I cleaned up my back-up copies? Any help will be apprecited!

A:USB Ports Have suddenly stopped working...

Have you tried disabling and re-enabling all of your USB controllers and ports in Device Manager?

If you don't know how to do get there...
Start menu > Right click on Computer > Manage > Device Manager

Moreover, to disable USB ports, go to the Universal Serial Bus Controllers button in the Device Manager. Right click each individual one and click disable. For each one. Then after each one is disabled, start from the top and do the same thing but click Enable this time. There are some dependencies in there sometimes that will disable more than one individual device, so be aware of that.

A:USB ports suddenly stopped working!!

Tell us the brand and model of computer, whether a desktop or a laptop, and the location of the usb ports... whether front or back, or whether we are talking about a powered external hub, or a multimedia box in the middle of the computer which has a 9 in 1, 15 in 1, or similar memory card reader with USB ports.
Are the USB ports built into the case, or on a pci card slot on the back of the computer.
Generally, USB ports do not fail. There are a few times when they do because any electronics made with chips, thyristors, and printed circuits can fail. But USB ports are among the most rare of failures... except when you are using multiports.
On inexpensive USB connections, they all share one connector... If you have four or five ports on one connector to the motherboard, then those in use will reduce the power that is accessible on lower quality units.

A:Solved: USB ports stopped working

It looks like a hardware problem, the restore would normally install the correct Usb drivers.

You can try running this, it's the chipset utility from Toshiba for your laptop, it should install Usb drivers :- http://support1.toshiba-tro.de/tedd-files2/0/csutil-20100512132816.zip
Unzip the exe file and run it.

If that doesn't help you may have to buy a PCMCIA Usb adaptor or similar.
Are there only 2 Usb ports on the laptop ?

Try unplugging all the power and let it sit overnight. Then plug in and try again in the morning. I've seen this work on occasion when all the USB ports suddenly don't work. For that matter, if simply unplugging AC doesn't work, might be worth pulling out any CMOS battery too.

Lately every time I try to connect a known working USB device, like digital camera, thumb drive, web cam, etc. I get a pop up window that says the device is not recognized. I have a printer plugged into a USB port, and it works, although I did have to reinstall the driver for it recently, because it too get the same error.
Is there a driver or drivers I should reload? What should I do to determine if it's really a hardware (port) problem? Devices will work on other computers, just not this Compaq desktop, 1.6Ghz, 2GB RAM, roughly 3 years old, XP SP3

Last night I was doing my usual gaming on my PC when I started getting popups about USB drives malfunctioning I didn t think much of them at the time Later on during the night my USB mouse stopped working I didn t think much of it and I switched it to a free port It started working again Then trouble USB ports working stopped suddenly started I plugged my headset into another free port it had been plugged into my Xbox it was working fine beforehand and started to watch an episode of a TV show The sound was horrendous It USB ports stopped working suddenly wasn t the file and it was not my headset as I tested it again on my Xbox and was working fine I switched USB ports It didn t work Then my mouse stopped working and my keyboard Funnily enough my USB phone charger still showed it was charging my phone and it still does right now I restarted my computer and at the POST screen it said a keyboard error had occurred or one was not connected When I start my computer with the keyboard plugged in the lights flash and the backlight comes on it is an illuminated keyboard so the blue lights beneath the keys work for some reason but none of the keys registered I had to dig out an old PS keyboard to get my computer to even get past the POST screen I did some reading around and saw a simple fix of turning off your computer and unplugging it from all power sources so I left it unplugged for hours while I was at work with the CMOS battery removed I got home and plugged it back in with just the keyboard and the same thing happened Backlights come on but nothing works It seems that the things I plug in to my USB ports aren t receiving enough power I am guessing that because after leaving my phone on the charger for or so hours it only got about of its charge Does anyone know what my problem could be I m going to go make sure all of my power supply cords are plugged in correctly and firmly It s a watt corsair power supply with the mobo listed in my spec thing I put at signup I ll post any requested specs after work tomorrow if any more are needed Short version USB ports stopped working and seem to not be getting any power to power the things I plug in nbsp

About 3 years ago, I gave my old Pentium 4 XP custom-built computer to a non-profit agency. It worked flawlessly until about 3 months ago when ALL of the USB ports stopped working. I checked the many posts on this forum for the same problem, and have tried

doing a system restore back to October;

checking to make sure the USB ports are enabled in the BIOS (they are);

deleting all the USB ports from Device Manager and letting Windows install them again (which it did);

reinstalling the chipset drivers.
None of these fixed the problem. Given that, the conclusion I come to is that some component on the mobo has failed. Am I right, or is there something else I need to try?

Just like that, the USB ports on my DV4-1435DX just upped and stopped.  I got messages that said that USB devices not recognized.  I tried uninistalling and reinstalling the drivers for the devices, thinking that somehow they were corrupted, but no go.  When I plug the USB devices (Logitech unifying receiver for my wireless keyboard and mouse and a Bluetooth adapter) into the docking station they work fine. And wouldn't you just know that my warranty ran out in July of 2010! Anyone else have this problem?  Is it going to cost me a lot to get this fixed?  I don't want to spend money for a repair that will end up costing as much as the notebook cost in the first place.

A:My notebook's USB ports stopped working

Problem solved.  After much researching, I found a five-year-old post that suggested I remove all the USB devices from the computer, turn it off and remove the battery and leave it for a bit.  Fifteen minutes later, I started it up, plugged my peripherals back in, and voila!  It was all working again! I'm glad it's back workng again, a laptop without USB ports was a major problem, and I envisioned expensive repairs that would have made it cheaper to just buy a new one. Whew!

Sounds like you may have overloaded the USB port and it is now toast.

I have an Inspiron M531R-5535 and about 3 days ago I noticed that none of the USB ports were working when I tried to back up my phone.  The next day, the Ethernet port failed.  It is not the wire, as it works on a different computer.  My WIFI is working fine, but it is really slow, so I would love to be able to get the port working again.  I am extremely unknowledgeable about computers, so any advice on this would be greatly appreciated.  Thanks!

A:The USB Ports *SUDDENLY* Stopped Working in my De...

Welcome to the Lenovo Community !
 
I am assuming that the two USB ports that are working are on the back of the computer.  That the two other back ones along with the front ones are not working.  Possibly there is a conflict with the hardware information stored in the CMOS which is preventing all the USB ports from working.  I would suggest you try clearing the CMOS to see if that will correct the problem you are having.  On page #26 of your model's Hardware Maintenance Manual show the location of the coin cell CMOS battery.  The battery's socket will either have a little tab to eject the battery or a slot in which you can use a small screw driver to lightly pry up the edge the battery.  With the machine unplugged remove the battery and press the power button for 15 seconds.  Then reinstall the battery, plug and then boot up the computer to see if the problem is resolved.  It is normal after clearing the CMOS to have to enter the time & date when the computer is booted  up.
 
The link below is for your model's Hardware Maintenance Manual. When working inside your system please follow all precautions and recommendations that are noted in the manual.

I have an older Dell Dimension 2400 running XP. The USB ports stopped working after I reinstalled XP. I checked the device manager and it says all the usb ports are working properly. Is there a way that they have been disabled? Is the device manager the correct place to check on them?

A:[SOLVED] USB ports stopped working

How do you know if your USB is disabled? What devices have you tried? You can try to go into Device Manager and right click the Enhanced Open Host Controller under USB and Uninstall it. Then Right click any device in the Device Manager and Scan for Hardware Changes, this should reinstall it. If it still doesn't work then go into the Bios and Disable USB press F10 to save then restart. Now Restart go back into the Bios and Enable USB pressing F10 to save. When you boot up it will load fresh USB drivers.

I am having an issue with some of my usb ports randomly stop working. the ports that continue to work are ones that have something currently plugged into them up to the point it's unplugged then that one also becomes unusable. so far the only fix i have
found for it is to completely restart my computer witch is tiresome and hard on my HDD's. i have checked the device manager and no errors can be found.
my operating system is Win7 Professional (64bit)

A:USB PORTS RANDOMLY STOP WORKING.

Hi ctrl003,
Please try the following methods to solve this issue:
Method 1:
Run the automated troubleshooter for your version of Windows.
For your information, please review this article

Open the Hardware and Devices troubleshooter.
Method 2:
Fix common driver problems

When hardware that's installed in, or attached to, a computer doesn't work properly, it's often because of a driver problem. Hardware and devices require drivers to work properly
with a computer. Follow the troubleshooting steps from this link and check if it helps:
http://windows.microsoft.com/en-us/windows/tips-fixing-common-driver-problems#tips-fixing-common-driver-problems=windows-7
Method 3: Reset the USB controllers.



Disconnect all USB devices.
Click
Start, type devmgmt.msc in the Search box and then press
Enter.
Double-click
Universal Serial Bus controllers in Device Manager.
Right-click on the
Generic USB Hub, click Uninstall, and then click
OK.
Repeat step 3 to uninstall all items under Universal Serial Bus controllers.
Reboot your computer, and Windows 7 will reinstall all USB controllers automatically.
What?s more, you can download and install the chipset drivers from the computer manufacturer?s website.

In addition, it would be helpful for future troubleshooting if you could help to collect the following information:


Did you get any error message?
Did USB ports work fine before? If so, what did you do after it worked well last time? For example, installed some software or changed some settings.

Regards,

Lany Zhang

Hello Dell community,

I was hoping you can help me with the issue I started having with my Dell Inspiron 660s (2013). None of the USB ports on the front and back, including two USB 3.0 ports on the back, can connect the keyboard or mouse. Mouse and keyboard (Dell, came with the computer) are working on any other computer, keyboard has a blue light on the num lock. Mouse lights up but there is still no cursor movement. Keyboard - no lights, and POST shows keyboard failure.
It seems that ports provide enough power to power on the mouse light, but not enough for the keyboard to work.
I reset CMOS, tried different CMOS battery, tried different power supply.
Any suggestions except motherboard replacement?

Thank you in advance.

I am having the same problem. I have been on Dell site and Microsoft site and what I am told is I have windows 10 auto update. After windows 10 updated I can get to the scene screen and that is it. I can not use my keyboard and mouse even though they work on other computers. I was told there is no fix for it yet. I was told that in a chat. Do you have windows 10?

I have a 32GB USB 3.0 pqi flash drive and it used to work on USB 2.0 ports just fine. I don't know why but it suddenly decided to stop working on USB 2.0 ports (still works on USB 3.0).

USB 3.0 port is not faulty.
USB 2.0 port is not faulty.

How do I get it to work with USB 2.0 again?

A:USB 3.0 pqi flash drive suddenly stopped working on USB 2.0 ports

I would copy the data off and store it someplace if possible. I would take USB 2.0 not working as a warning something may be breaking down in the drive. It might only effect USB 2.0 but it's difficult to be sure.

I'm not a hardware guy so I'm not sure if you can test them with a multi-meter.

A:Toshiba Equium A200 USB Ports have stopped working

Riff have had a bit to do with Toshibas and have an A200 myself now where did you get the drivers from??
What we need to know is the PART NO see pic



Now being quite an older machine it might be down to wear so lets hope it is drivers though I can get some disassembly guides for you.

A:Solved: All my USB 2.0 Ports (and possibly my modem) have stopped working - Help!

The monitor has nothing to do with your problem. Your Ipod charges via the USB so the 5 volts is there. Have you looked into the Device Manager and see if your USBs and modem is listed as a "problem device"? (RIGHT click My Computer choose Properties, then the Hardware Tab then the Device Manger Button. ) Is your Norton up to date?? It must be up to date with the latest macro or viris sig. to make sure you are virus free. You would be surprised by the virus' that slip in and infect systems. While this could be a motherboard failure, I would try removing the modem and the USBs from the Device manager first and see if Windows will set them up on the next boot. You may need to supply a driver for the modem but XP should set up your USBs without any prompts.

A:USB Ports Stopped working after an Internal Power Jack is replaced.

It sounds rather as if your new part somehow isn't diffusing 5 volts to the correct circuits, which is what USB relies upon. Could be a bent pin or misaligned plug on those pins, or a broken wire.

Soltek 915GPro-FGR Mobo
P4/2.8 GHz 800M LGA775
WindowsXP Pro SP2

When I first built the machine all the USB ports worked. After installing Windows they stopped. I reinstalled the Intel Chipset Driver and they worked for about 2 weeks. Today they stopped and will not work even after I reinstall the Chipset Driver.

Any ideas?

Thanks.
 

A:SOLTEK 915GPro-FGR Mobo....all USB ports stopped working today.

a few years back i had basically the same problem on a supermicro 370ssa, 815e chipset. was running win 98se, but still same problem. turned out there was a hardware failure, i had to buy a usb pci card. i'd try it with an extra usb card installed and see if that too went down. also consider updating your bios and drivers and windows to thier latest.

A:Wi-lan (something Like That) Randomly Stopped Working

Hi MuffinMan,

I have the same problem and would love an answer as well! When this happens to me I usually use a cord to plug in to the router and it seems to fix the wireless within a few hours. But this will become much more annoying when the weather warms up and I will be outside with my laptop!

Hopefully someone will be able to offer some suggestions!

Hi I have a Samsung ES digital camera with which I use a Sandisk Ultra gb class sdhc randomly SD card stopped working using windows I inserted it into my laptops sd card reader and could view the files For some reason after trying to select certain files and change from tile view to list view the window froze for a little while I could see about icons then when SD card randomly stopped working scrolling down the remaining files didn t have an icon Selecting one of these to open and in the file viewer it said this file may have been deleted or removed from what i can remember I then removed the card SD card randomly stopped working Using safely remove hardware tool Then upon reinserting the disk i get the message You must format the disk in drive before using it When inserting into my camera it says card error But if i format the card all the current data will be erased I then used a software called Recuva to try and recover some files before formatting but nothing was found even in deep scan What can I do I really need those pictures video clips Also i noticed a funny thing when i first inserted the card There were about folders named as letters N O No idea how they got there but when opening it would let me in saying those folders may be on the harddrive instead There was also two files with no file extensions with just symbols in the name The only thing I know of is changing the rotation of a few images last week from my laptop - which then couldnt be viewed on my camera Thanks in advance nbsp

A:SD card randomly stopped working

Sadly you are probably out of luck, SD cards like all storage devices fail all the time.

I'd try PhotoRec first: http://www.cgsecurity.org/wiki/PhotoRec
PhotoRec guide: http://www.cgsecurity.org/wiki/PhotoRec_Step_By_Step

You can try these programs as well and see if they have any better luck then Recuva: http://www.computerworld.com/s/arti...covery_tools_for_SD_cards_USB_drives_and_more

Just as an FYI, you really shouldn't work on the pictures while they are on the SD Card, you should copy them off the SD before editing them. SD cards have very limited read/write cycles. Most times once a photo is edited(ie. rotated) many camera's won't open them anymore. Additional, just like the SD has failed so can your computer's hard drive and you can lose everything just as easily so hopefully you have a very well established data backup for your computer as well.

I have a windows 8, Packard bell laptop.
I forgot to turn my laptop off, and instead left it on sleep mode for a day or so. When I came to enter my password, my keyboard was not working, and I have had to use the on screen keyboard to type.
I have rebooted, and have checked things like Filter Keys.
When I tried again today, I managed to type a couple of random letters in the search bar, while the laptop and windows was still starting up. Once everything was fully loaded, I was unable to type anything more.
Does anyone have any hints at all?.

On Thursday I turned on my Xbox and found my xbox live wouldn't connect to the internet, thought it was strange so I checked my IPhone, same thing.I go and check my school laptop and it also would not connect to the wireless. However, my personal laptop which is connected to my router through the Ethernet cable worked fine for a few days. Then the internet on it went out, which my Windows troubleshooter told me was my DNS server not responding. Which I fixed by changing my preferred DNS server to 208.067.222.222 which fixed it on my laptop but has not fixed the wireless. I have a Westell Versalink Model 327W router if that helps at all.

You will definitely want to perform a reset on the router using the reset button on the router. Router's typically will lose wireless while the wired connections stay active.

Sometimes a 30-30-30 reset is required to fix these types of problems.
