Unknown device shown in device manager

Q: Unknown device shown in device manager

Does anybody know what this device does. It's located under SCSI and RAID Controller, it's called AWFOEXCS IDE Controller. I have no idea what the hell is that.

Preferred Solution: Unknown device shown in device manager

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 (This link will automatically start a download of Reimage that you can save to your computer.)

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.

I have a Toshiba laptop model L -ES I had Windows Home Premium bit installed on here but decided to reformat my hard drive using Windows Devices in Device Device Unknown Hidden Manager/Show Ultimate bit After the reformat was finished I ran Windows Update and it found several items to download and install for me I noticed that it also found optional items to download and install for me so after all the important updates installed I ran the optional updates After all of this installed I checked Device Manager to see if there were any errors and I found nothing I assumed everything was fine I decided to check Devices and Printers and Unknown Device in Device Manager/Show Hidden Devices under my laptop icon there was a yellow icon with an exclamation point on it I decided to run the troubleshooting option when I right-clicked the icon it gave me a solution to download a Toshiba password utility program so I did that and nothing happened even after restart Same Unknown Device in Device Manager/Show Hidden Devices icon appeared When I clicked on the icon a second time I noticed that the model of my computer at the bottom of this window changed from L to TIAS I have no idea what this is I decided to do another reformat on my hard drive This time I ignored the optional updates I checked Devices and Printers again the same icon appeared but the model of my computer said L like it should There is something in the optional updates that is changing this Could it be the Intel chipset driver that the optional update is pushing I'm not sure I went back to Device Manager this time I clicked View and put a checkmark next to Show hidden devices and I found it In Other devices it says unknown device After right-clicking on this and checking the driver details I got a hardware ID that says ACPI TOS I did some research and was told that it could be my Intel chipset so I went to Intel and their website did an automatic scan of my system It found a few things so I installed them and rebooted the laptop Doing this did not fix the problem Is there a way to figure out what this device is It doesn't seem to be hindering my laptop but being a perfectionist it is really bothering me One thing I wanted to add could it be a USB device I noticed that I do not have my media card reader drivers installed but yet when I put a media card in it reads it just fine or maybe the USB camera installed on the lid of the laptop After checking my imaging device it looks to be installed has to be something

Hello I recently put together a new computer and in the process of of installing the USB connector Working - Front USB Device not Device" Ports "Unknown in Manager from the front of my GX case I Front USB Ports not Working - "Unknown Device" in Device Manager either bent numerous pins on the motherboard USB header or the motherboard shipped that way and I inadvertently made matters worse Anyway that header on the motherboard is without a doubt unusable Since I don't really need the USB functionality I bought a USB - gt adapter cable connected one end to the connector on the front of the case and the other end into the USB header on the motherboard Unfortunately when Windows boots and I plug a device into the front ports of the case Windows detects the front USB ports as Unknown Device within Device Manager yet says the driver is successfully installed I've already downloaded the most current Intel chipset drivers for my motherboard deleted and reinstalled all USB drivers and all rear USB connections are working perfectly fine - it's just the two front ports that are connected from the case to the USB ports via the adapter cable I've tried both USB headers on the motherboard and I've tried plugging in several devices to the front USB ports and this problem still persists I've ensured Front USB Ports not Working - "Unknown Device" in Device Manager the connection inside the case is solid yet I cannot get Windows to recognize the front USB ports However I have confirmed that power is being sent to the front ports because it charges my phone when I connect it to the front USB ports via micro USB connection As a result I'm inclined to think this is a Front USB Ports not Working - "Unknown Device" in Device Manager driver issue rather than a hardware issue Any ideas

How do i figure out what driver or even component windows wants software for when in the device manager under other devices it lists an unknown device and windows update cannot find anything.

Oh and is it appropriate for me to use this topic to ask another question regarding explorer.exe as while i am inside a folder i delete (by choosing delete from the context menu in the tree view) while inside that folder on this particular laptop PC explorer. always crashes, collect information, sends it and restarts explorer. I have not experienced this problem on any other pc running any version of windows 7, oh and the same happened with build 7264 x32 and the current install of build 7600 x64.

Hi Team, Please help me to resolve a problem, I've one unknown device in device manager I've tried to update drivers but issue didn't reolve after it. Can you help me to figure out what is this unknown device.
Relevancy 102.77%

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.

DO NOT REMOVE ANYTHING YET. I will advise if anything needs removed when I receive the log.

Hello Native,
Go in to your Bios, ( normally delete on boot up), and see if you can disable your on-board video card.
Its the only thing i can think of, I'm assuming you have the latest drivers for the HD 4350 card.

So, my webcam works fine, except for the built in microphone. It is a Logitech 'Quickcam for Notebooks Pro' which is a bit outdated. I looked for the most up-to-date software but I guess they don't have drivers specifically tailored to handle Windows 7.

Anyways, my webcam mic shows up in the device manager and is not disabled, but for some reason, it doesn't show up anywhere else, most importantly in the sound settings, under recording devices. What is the issue here? Thanks in advance for any help

I just reinstalled Win 7 Pro on my Elitebook 8460p. When I open the device manager, I do not see any network adapter, wireless or otherwise. How can I find my wireless adapter, so that I can install it and if needed download the appropriate drivers?  

A:No network adapter shown in device manager

Hi: You should see a device labeled as a Network Controller under an Other Devices category in the device manager. The Network Controller will have a little ! mark inside a yellow triangle. That is the wireless card that needs a driver. Since there can be more than one model wireless card in that notebook series, I don't know what driver you need to get the card to work but that is easy enough to find out. Please post the hardware ID for the device you see listed as a Network Controller. To find the hardware ID, click on the device labeled as a Network Controller. Then click on the details tab at the top of the network controller window. Now you will see a Property drop down list and it will be set to Device Description. Drop down on that list and select the 2nd item (Hardware ID's). Post the top string of characters that you see in the window.

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.

Back in the day when I first installed windows 8, the card was detected and it automatically installed Nvidia drivers from Windows update but not this time.

Anyone know how can I get the card to show up in the device manager?

On a fresh clean Windows 8 image, my software driver (signed) installs fine and shows up properly in the Device Manager. However once i uninstall it , subsequent reinstalls show up as 'Unknown Device' in the Device Manager.

From the device details, I find that it refers to /looks for the .inf file in c:\windows\inf folder but the file itself is missing from the location. The FileRepository has all the required files. But trying to update from there also fails.

Could anyone help me with troubleshooting this problem. What could be going wrong.

I have two devices IEEE 1394 and Realtek RTL8139 listed under UNKNOWN in device manager.
I have deleted ALL previous unknowns (about 7) and when I reboot these two are found and drivers are automatically installed but they still end up under UNKNOWN. I tried reinstalling a new driver and it did not because what was installed was determined to be the best.

SO........ Windoz XP sees the devices, installs drivers, but still lists them as unknown and the LAN doesn't work.

I must say that this started after a McAfee update which I uninstalled - but problem still exists.

I clean installed an ASUS Laptop Model a2500h, Windows XP Home edition SP3.

There are two drivers that I can't seem to locate. The Hardware ID's are as follows.


I know ASUS often has utility programs that show up as drivers, for example I had the ACPI\ATK0100 which was listed as an UNKNOWN DEVICE, and I installed that utility fine.

I am just not sure about the other two. I was told on another forum that it could be something to do with the sound drivers, but I suspect it is one of ASUS' little utility programs.

Any help would be appreciated. Also if any additional info is required, let me know and I will post it.

To me it appears to be a virtual CDROM drive installed by some game/software you recently or in the distant past installed. Just brood on it.

Without knowing the source - which you only know - the only brute force method of getting rid of it is to try a system restore to an earliest point of time available which may or may not get rid of it. Depends when it - the virtual drive - was created.

 So recently I've been receiving driver issues with my PC. I'd be working in FL Studio 12 while in a Skype call with my friends, then all of the sudden the whole entire PC freezes. So, to get a better idea on what's going on I went to the Device Manager, since I figured it might be a driver malfunction. I spot under "Other Devices" some suspicious looking drivers that I do not recognize. I think it might be an ASIO Audio driver that was installed with FL Studio 12, but I am not sure. Here is some more details:  This is details and value of the drivers.--This is general information about the drivers.  In addition, these drivers aren't digitally signed. There's no dates on when it was signed, and the signer is unknown.

  So, I was working in a digital audio workstation while in a Skype call with my friend, and all of the sudden the PC just freezes. I tried to speak, but he couldn't hear me. So, I figured that an audio driver installed with the DAW might've contributed to the problem. I went to the Device Manager and saw two unknown devices in the "Other" category. Yet, I don't know what they are. There's really not so many details or information about the two drivers. There's no manufacturer names, descriptions on what they do, and even more suspiciously, they aren't digitally signed. However, there is interesting values they're set as.  One is ROOT\MEDIA\0001, and the other one is ROOT\MEDIA\0002.  In addition, they don't have the necessary drivers, as I googled "Error 28". In addition, I think these drivers are the culprit of my OS malfunctioning.

There isn't any current function that we're using that isn't working so I'm not sure what category of thing these are and the hardware ID's aren't of the expected format so they don't reveal anything either.  Everything is unplugged and wireless is turned off(airplane mode on) so these are not external items.

I have a dv7-2170us laptop.I performed a clean install with Windows 7 Home Premium 64-bit.I used the drivers for this laptop model from the HP site.I'm getting a few unknown devices in Device Manager.I've tried un-installing the devices and re-installing to allow Windows to re-detect but no drivers are found.  See pictures below, what devices could these possibly be referring to? I have all the necessary drivers loaded that I am aware of and I installed any driver that looked valid from the HP drivers site.

A:Unknown devices in Windows 7 device manager - dv7-2170us

EDIT: Everything works!  Thanks for the tip Daniel.  I googled how to identify hardware id's and came up with this site , punched in the device id's and bam, it WAS the card reader.  Weird because it was working perfectly.  But I downloaded the driver anyway and re-installed and this resolved the issue.  ============================================= I tried the Intel Chipset Utility, didn't work. Here's the hardware id's though:  If you look closely you'll notice that each of these devices are in fact different.

Hi all please see attached dxdiag for my system specs note that this is a big desktop PC this morning i noticed a device in the device manger which isn't working properly Normally if it's not a major issue i'd consider that sort of thing a silly nitpick However i'm currently experiencing a major problem which manager: controller, device in USB host Code 43 Unknown shall have its own thread later and i need to start eliminating possible suspects i tried to research this little issue and i found some steps that seem really good for major discrete components unfortunately usb host controller is a generic entity i'm not honestly sure if it even corresponds to any particular usb headers or external ports I've already tried the basic steps of disabling enabling it un reinstalling the device restarting the computer leaving it powered off for five minutes etc anyways details the device is listed under the Universal Serial Bus controllers section of the manager as Unknown Device When i open up the properties menu i see the following info Device type USB controllers Manufacturer Standard USB Host Controller Location Port Hub Device Status Windows has Unknown device in manager: USB host controller, Code 43 stopped this device because it has reported problems Code going by instructions i found Unknown device in manager: USB host controller, Code 43 elsewhere i was trying to hunt through the details tab for the hardware ID Unfortunately that option only reports the value USB UNKNOWN so far the only ray of hope i've found was some mentions of a problem related to laptop batteries unfortunately this is a desktop PC so that advice wasn't applicable please provide advice and troubleshooting steps

A:Unknown device in manager: USB host controller, Code 43

Well...the first thing I would delete all "controller" items under USB in Device Manager.  Not bother with "hubs" or any other listings, just the items with "conrroller" in the listed description under USB.
Reboot after removing all such.

I have a Dell Inspiron M731R laptop upgraded from Windows 8.1 to Windows 10 Home 64-Bit that suddenly quit connecting to the home network. Was using wireless, so switched to an Ethernet cable, but still no luck. I just discovered that ALL of the network-related devices are now listed under an "Unknown" tab in the Device Manager. A check of properties of each item in that folder says they are all working properly, but that obviously isn't the case. I tried uninstalling each of the 4 items, but when they are recognized again they still show up under the Unknown tab. Any suggestions would be welcome.

A:Looking for advice on a VERY suspicious "unknown" entry in device manager

I will start my own question thread if you want but I believe we have the same trojan.*A word about this trojan: after detecting it by running rKill to stop it, then SuperAntiSpyware to detect it, I reboot and delete/quarantine right away, allowing for the reboot. Upon reboot, I run rKill again then SAS again and it finds it again every time. I backed up to my second drive then removed it and reinstalled windows 7, 64-bit. So I reinstalled windows and it seemed to still be there after a short time of being on the network... but I was able to remove it using a combination of ComboFix, rKill and SAS. But, when I plugged in my second drive again BAM! it was back and irremovable again. It could be the virus is on the network here at home, or the second hard drive with my backup, or I could have gotten it from the internet while I was grabbing drivers. Regardless, once the PC is clean I will again clean reinstall, I just need it to be clean first so that I can perform the backup without backing up the trojan!*I ran a scan on the other household computers and they all have it. So, I will disconnect the network cable from this computer and just transfer files to it from another (known clean linux PC) computer until I know how to fix it (so it won't get reinfected by the others). Then one by one fix the rest (then connect them to the network again).I also have many of the same files (see here):C:\Users\admin\AppData\Local\Temp\RarSFX0>tree /fFolder PATH listingVolume serial number is F4A5-1E44C:.│ curo.reg│ extra.dat│ lmro.reg│ lmroe.reg│ nircmd.chm│ nircmd.exe│ nircmdc.exe│ pev.exe│ prep.bat│ proxycheck.exe│ rkill.bat│ rkill.reg│ s.inf│ sed.exe│ serv.dat│ sh.vbs│ swreg.exe│ userinit.exe│ winlogon.exe│ wl.txt│├───h│ explorer.exe│ iexplore.exe│├───nird└───procs iexplore.exe proc.datC:\Users\admin\AppData\Local\Temp\RarSFX0>This seems to be a new Trojan.Agent/Gen-IExplorer[Fake] type of trojan.

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. All other usb devices (mouse, keyboard, web camera, APC UPS, external drive, printer) work fine. How do I get rid of this nuisance so that it doesn't reappear?

Dell Vostro 1400, Core2Duo. Installed Windows 7 64 bit a year and a half ago. For those not familiar, the Vostro is not entirely compatible with 64 bit, so the drivers are a little hit and miss.

Computer runs slow sometimes, has since the install. I don't think I've ever seen the yellow triangles before, but I may have never looked at the device manager ... the computer is a secondary machine in the house.

My question is, do these indicate a performance problem or can I ignore them and assume the computer is working as best it can?

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".
