Solved: Unknown USB Device on All Computers

Q: Solved: Unknown USB Device on All Computers

Hi all,
My friend gave me her USB device in tears because after an improper eject, it is now unrecognizable by any of the PCs she connected it to.

The error in the device manager (in WinXP) is "Unknown Device" and that's what popped up after I first plugged it into my PC.
I've tried disabling, uninstalling, updating drivers - the typical slew.... is there any chance it, or the data salvageable?

I haven't tried it on my CentOS system yet -
Any thoughts are greatly appreciated!

Hi folks , I'm having the devil of a job trying to get the sound running on a friend's PC . XP Pro (32-bit) installed on Asrock Conroe Presler 775i945GZ (64-bit) motherboard . I've installed chipset and realtek audio drivers appropriate to the mobo (from Asrock site) but Device Manager still shows an unknown PCI Device under Other Devices and onboard sound isn't working . There are no PCI cards installed and onboard audio is enabled in BIOS . Could there be an issue with a 32-bit OS being installed on a 64-bit mobo ? I wouldn't have thought so but have little experience with 64-bit .

Any thoughts on this would be greatly appreciated

Hello, I finished re-installing windows XP and at first after getting all the drivers, it said I had an unknown driver which was the last one and it was the audio drivers. Then, I had every driver installed and the display driver was by microsoft and I needed the CCC to go with my driver, so after installing Ati's driver for ATI RADEON 9600XT, I keep getting an unknown device when I boot up my PC.

It says the location is on ATI RADEON 9600/9550/X1050 Series.

Thanks in advance.

I run into this problem often and it takes me a great deal of effort to resolve it, in most cases. After formatting and reinstalling windows (wich we do for every new employee) I have to reload motherboard drivers. More often then not we don't have the mobo cds and are forced to get each one manually. There is a device left in the device manager labeled "unknown device." My question is this. Is there an online resource that can tell you what the device is from its id listed under properties? The only resource I have found requires a device ID that only propagates if windows recognizes that device in the first place. The unknown device id's usually look something like this ATK0101/110101
If anyone knows another method to resolve this issue that would be cool too. I usually take screen shots of the entire device manage list before formatting, but its not much help.

A:[SOLVED] Unknown Device

I've come across this problem a few times too. I'm sure your aware of the driver utilities that show you a list of all drivers needing to be installed. I would start by finding the utility for the mobo that allows you to choose from a list of drivers. Chances are it's probably some modem floating around or something.

I'm not sure if there is a database out there for this situation but i'll keep looking. Also if you do find the correct driver, I would slipstream a copy of Windows that has all drivers you need on it (assuming most of your builds have somewhat similar hardware)

I just did a fresh install Windows 7 and installed all updates and drivers. Although, I noticed an unknown device in Device Mamager. It's an Intel(R) ICH10 LPC - 3A18 Interface Controller as written in properties. I installed every damn thing about it (actually the Intel_ChipsetInf_V9111014_XPVistaWin7), but it seems that I'm missing something. Also, so far system is running smoothly, but I want to be sure that no harm will be done from this issue. Any ideas why it's marked as unknown all the time?

Have you run Windows Update? Do so manually and check the optional updates once he scan is done, there should be an ASUS ACPI driver listed, install that and see if it clears the error. The driver is also posted on the ASUS site under I think utilities for many motherboards.

I'm having issues getting my USB ports to work. They're definitely getting power but not registering any USB device being plugged in. I've checked in the Device Manager and I see two UNKNOWN DEVICE messages with ERROR CODE 43..."Windows has stopped this device because it has reported problems. (Code 43)".
I've tried full shutdown and battery removal...failed.

Uninstalled each USB root hub from the device manager then restarted computer for full auto re-install...failed.

Downloaded Hardware Identification Tool and used it to download correct drivers (as confirmed by the manufacturers website) and failed as well.

Can anybody help me with this issue by chance? Would be greatly appreciated.

I did a wifi device scan using SoftPerfect Wifi Guard and have a device I do not know. I have 4 in total laptop, router, BB phone. The 4th is a Hon Hai Precision device. The only other device I know of is my satellite modem, hard wired to router. I live in a very remote area and have no neighbors close by.
I assume that there actually is a 4th unknown device. How can I track it down?

A:Solved: Unknown WiFi device

Hi, and welcome to TSG.

It looks like the software detects both wired and wireless devices on the the same network.,14397

Is the wired satellite modem connected to the LAN or WAN side of the router? If it is on the LAN side, try disconnecting it and rerunning the scan.

If it isn't the modem, does anyone in the house have any portable Apple devices? It is my understanding that Hon Hai Precision supplies the WiFi hardware for some Apple products.

Are you using any WiFi encryption?

I have a HP630 notebook with windows 7 Home Basic OS. I upgraded it to windows 7 premium and downloaded all the drivers. These driveres were installed properly. My laptop was working fine until recently. Now the webcam is not working. Whenever, I open Skype, my webcam does not turn on and an error message is shown ' Webcam is Off. If you have integrated webcam, turn it ON'. Secondly, I noticed that device manager shows " unknown device" in USB devices. When I checked for it error code it indicates " windows has stopped this device (error code 43). I feel that stopping of webcam and unknown device error are two issues which are related to the webcam malfunctioning. I remember that webcam was working OK earlier.

Hiya all,

I just installed Windows Xp on a puter. After installing all the drivers including the video card drivers from ATI's website the computer discovered an "unknown device on ATI Radeon X700"

The motherboard is a gigabyte 8I865GME-775-RH and obviously a X700 Radeon Video Card. AGP drivers, chipset drivers and the like are all installed. The video card showed up as an unknown device when I first installed, I put in the catalyst drivers and it detected successfully, upon reboot this new unknown device came up and I can not seem to find any drivers for the thing. I tried reinstalling the catalyst drivers as well to no avail.

I have now installed this and connected my PC (via USB) and XBOX360 (via ethernet) to the Home hub, l and although I have to wait for my line to be optimized, everything seems to be working well.

However, when I check on y network status, using the BT Broadband Desktop help utility, it shows I have an UNKNOWN DEVICE connected to the router along side my PC and XBOX360.

I have tried to obtain assistance from BT themselves but they simply told me to ignore the unknown device, as it will not cause any harm!!!!

What am I missing here? I bought a Mitsumi external usb floppy drive on eBay. Plug it in either an Intel or nVidia chipset desktop machine with XP SP-2 and I get the Found New Hardware and Unknown Device boxes at the toolbar. This is confirmed in Device Manager. The enclosed floppy is a model D353G. The enclosure is marked "Generic USB FDD (UD-376)." The software known as "USBDeview" can tell me little about it, but it does see the firmware as "1.03" and lists vendor and product ids.

Since I shouldn't need USB drivers for XP with SP-2, am I missing the obvious, or have I been screwed by a zealous seller? tia

Hi all,
For the last several weeks now on startup on my laptop running Vista I keep getting a pop up stating new hardware has been detected and do I want to install the driver for it. I select yes windows looks for a driver but cannot find one. I have looke in device manager for anything that is amiss. And under other devices there is the yellow mark stating that there is a problem. The only thing I can find out is that it is a plug & play item, no specific name or anything to tell me what it maybe. When I select Properties for the said device the details I am given are \Device\00000025 and that it is not configured correctly. Is there anyway I could find out what this is ? Or should I uninstall it and reboot, and hope that the problem gets fixed on startup.

It's reported location is within the front USB root hub but I haven't changed there anything lately. The device status reports "Windows has stopped this device because it has reported problems (Code 43)". I can uninstall/disable it but it will get picked up again the next time I reboot.

Hi everybody.

I just bought myself a Powercolor Radeon HD 4890 yesterday. After installing the card and the required drivers everything works like a charm. However, every time I start up my PC I get a message saying that a new device has been found on my system. On checking Device Manager I found an "Unknown device" entry under "Other devices".

I'm attaching a screenshot of Device Manager.

Are there any drivers I'm missing? It only happened after removing my old card (after uninstalling all its drivers) and installing the Radeon.

Any help is greatly appreciated.


A:Unknown Device In Device Manager After Installing Radeon HD 4890

I have a Powercolor Radeon HD 4890 (I also have a Gigabyte 4890 and XFX 4890 in two other PCs). I think you need to install the latest ATI Catalyst Suite. You may have installed the driver only package. Anyway, I think it has to do with the HDMI capabilities of the card. High def sound is built into the card (the HD part of the card name) and the HD sound driver is part of the Catalyst Suite. When you use an HDMI cable to an appropriate display, HD sound is also transmitted through the same cable from the Radeon graphics card.

Of course, be sure to install .NET Framework 2.0 as it is required before you can install the full Catalyst Suite. The HD sound driver won't install without it. At least I had trouble before I installed .NET 3.5. I went to Windows Update and installed .NET Framework 3.5. 2.0 is included in that update and 2.0 wasn't available separately.

A:Unknown USB Device (Device Descriptor Request Failed)

Is there only one USB port on the right hand side? Sometimes manufacturers connect internal devices via an unused USB port internally. USB ports are usually in groups of two, seeing only one port is usually a sign that the wiring has been redirected internally to something else like a Bluetooth adapter or wifi adapter. It may even be a card reader or touchpad. Is anything like that not working? If it is start looking for a driver for it.

Fresh install of Windows 10 and the last driver I need to sort out is the above.

I believe it is my powered USB 3 hub to which I plug in my keyboard and mouse. Technically it is working but I don't like seeing yellow triangles on devices.

So are there any fixes?

A:Unknown USB Device (device descriptor request failed)

If it's a generic USB 2.0 Powered Hub then technically there's should be no drivers needed by Windows, if it's a USB 3.0 Hub then I'm unsure (since I don't own any USB 3.0 Hubs).

Might be a Windows bug, basically Windows can't find the description information to display the Hub's name in the Device Manager example: Generic USB Hub, Root Hub Device, etc....

I'm pretty sure everything is working as should, you're good minus the minor annoyance if all device connected through the USB Hub is recognized by Windows; if you right click Properties on the yellow triangle it probably says "The Device is working properly".

A:Unknown USB Device - A request for the USB device descript

I'm too of opinion that it's a power issue. Laptops are not known to have much power thru USB ports, not even some desktops for that matter. Possible solutions: If that laptop has USB3 port you can try it in there, it gives more power and is compatible with USB2. Another one is to ad external power to the drive. One of the USB connectors on the twin cable has only two connection tabs and is for extra power to device. That one can be connected to universal USB charger for phones etc. That's how I solved a problem with a HDD in external enclosure.

Hello everyone, I hope you could give me some clue that may have caused the appearance of an unknown device. All information here : An unknown device appears

First, That was solved by uninstalling and rebooting, did not appear anymore. But as I said in the previous topic, that solution does not leave me entirely peaceful.
Since when searching for information on the issue, some say it may be a virus. But also by the HWMonitor. I prefer it was caused by HWMonitor instead of a virus.

Can give me a hand to remove my doubts about whether it was caused by a virus or not.

I scanned all the PC with ESET 6 and nothing.

Thank you for your time and help

Sure, lets begin:

1.) Download herdprotect: (choose the portable version)

Download herdProtect - Free Anti-Malware Platform

2.) Run the scan.

3.) When the scan finishes, save the results per the screenshot below. Then upload the log here.

Hello all,

I hope this is the right forum for this.

That said, I am running Vista with a wireless interner connection.

When I check my "Wi-Fi Intrusion Detection" (Trend Micro PC-cillin), I see multiple unknown computers connected to my computer.

The "status" in unknown, but IP addresses are listed.

Looking up the IP addresses, some are within a few hours of my home, while others are over six hours away!

Now, when I check my "network" from the start menu, and then check "network and sharing center", I only see:

My computer---Network---Internet.

I do not see multiple computers here.

I have file sharing turned off.

I use the wireless internet for online gaming; maybe this why I see so many IP addresses on the "Wi-Fi Intrusion Detection"?

I use a WPA 26 Hex character password for the router.

Thanks in advance!

A:Unknown computers connected to your network

You need to check your router log. That'll tell you if your intruder is on the network... but I doubt hey are.

Sounds like you were scanned and the program reports it weird. As you wouldn't see a unique ip as a wireless attack. Theyre Probably pings from your isp.

Though I'm alittle confused on your setup.... Is it a desktop/laptop connecting to a wifi router? Or through a mobile wireless signal like a smartphone.

My OS is Vista home premium, security is Trend Micro Internet Security Pro. In the past week using the home network function in Trend Micro, unknown computers have been showing up, I now have twelve unknowns blocked using the network map function, all have different IP addresses, some are close in numerical sequence. I don't know what other info. would be needed to figure this out, how can I get out of this mess. Scans in safe with Trend and Malwarebytes show nothing, Windows safety scanner shows nothing, no open ports. I have run threatfire, nothing. Don't know what to do, any help would be great.

Hi NiGHTS, and welcome to TSG.

Do your parents have any kind of encryption enabled on the wireless router? If not, their wireless network is fully accessible to any one in range that wants to use it.

Hello all,

My computer is located in my basement, with my video game system (Xbox 360) is located on the floor above it.

I use a wireless connection to play the 360 over Live...

I just checked my Wi-Fi Intrusion Detection, and I have several unknown computers connected to my network.

I checked the IP address is in my small town, a few about an hour away, and one address is from several states over.

I looked at my Network and Sharing Center...I only have my PC connected to "gateway", which is then connected to the Internet. My file sharing is turned off, and I appear to be operating on a private network.

Should I be concerned about any of this?

Thanks in advance!

I have recently bought a reconditioned Fujitsu Lifebook S6120.

I have successfully installed all the drivers from Fujitsu's web site. But there is still one "unknown device" - USB BT. Since the machine has an original Bluetooth sticker and the software does not see bluetooth, I suspect this may stand for USB Bluetooth.

The device has the ID


Does anybody know what this means?
Are any drivers available for this device?
I have used the XP device manager's WEB search,
and manually Fujitsu's site and but not found anything.

For the moment I've disabled the device to stop getting repeated "found new hardware" messages.
Many thanks,
Oliver Pretzel
