I upgraded to Windows 10 a while back. Every time I open the computer I get a pop-up notification telling me the USB device is unrecognized. I have no USB devices in any of my 3 USB ports.
I sent my computer in twice. No help. They just uninstalled everything and reinstalled everything and told me it should be fixed. It is not. I then went about updating every driver in my Device Manager. I uninstalled the Unknown USB Device and then updated
other drivers. Certain drivers (such as PCI Express Root Port #3 - 9C14) when updating would also reinstall the Unknown USB Device, which I would then uninstall and keep working down the list. At the end of updating EVERYTHING I scanned for hardware changes
and "found" the Unknown USB Device. 
From what I can tell, and I know very little about this stuff, my computer can't name one of my USB ports. Since it can't figure out what it's called it can't download the proper driver for it. Since it can't download the proper driver it can't work properly.
The practical result from this is that one of my three USB ports does nothing when I put in any USB item (connect my android phone, thumb drive, presentation clicker, etc).
I've looked on tons of forums. My current thought is that if I can tell my computer what the deice is or download the right driver and tell my computer to use that driver for this device it should solve my issue. But I don't know how to know what the name
of the USB port should be (I imagine it woul... Read more

Hi HP Support, I've recently been given a laptop to fix, the hard drive needs replacing, but I need to enter the BIOS and can't as the password is long forgotten. Is there any chance I can get a hand  resetting the password? Cheers! Toby

A:Unknown BIOS password on ProBook 430 G3

Hi, Unfortunately,  business machines such as Probooks or Elitebooks have more stringent security than consumer models - they don't produce 'halt codes', the password cannot be derived from the Serial No. and the code is stored in non-volatile memory so removing the RTC cell will not reset the password in this case. If you Contact HP Business support they should be able to send you a customised SMC.bin file which you can use at boot to reset the password. Regards, DP-K

Our school currently has 800+ Probook 640 G2s and I've been repairing them but starting to come across a trend. The device won't come on AT ALL. I've replaced motherboard, power button board, tried different battery both in and out, reseated ram and tried the other location, different SSD and power supplies. I've almost built a new one a few times. We sent one off for them to repair at Depot so I could figure out what I'm doing wrong and the repair sheet came back with 3 parts. 845847-601 System Board (I know what this is obviously even if that part number doesn't match anything for the laptop). 846867-001 Hardware, HDD Bracket / Screw / ODD Bracket / Smart846868-001 Hardware, HDD Bracket / Screw / ODD Bracket / Smart The two above parts however I don't know what they are. Our machines have SSDs in them and there's no bracket. It plugs straight into the MB and 1 screw holds it down. I've tried the part searcher and it finds nothing (not even for the system board number). If anyone has any ideas it would be MUCH appreciated.

I recently put together a new computer, and in the process of of installing the USB 3.0 connector from the front of my GX500 case, I either bent numerous pins on the motherboard USB 3.0 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 3.0 functionality, I bought a USB 3.0 -> 2.0 adapter cable, connected one end to the connector on the front of the case and the other end into the USB 2.0/1.1 header on the motherboard. Unfortunately, when Windows 7 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 2.0/1.1 ports via the adapter cable.  I've tried both USB 2.0/1.1 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 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 m... Read more

I have a Toshiba laptop, model L505-ES5018. I had Windows 7 Home Premium 64 bit installed on here, but decided to reformat my hard drive using Windows 7 Ultimate 64 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 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 gave me a solution to download a Toshiba password utility program, so I did that and nothing happened, even after restart. Same 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 L505 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 L505, 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, th... Read more

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.

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".

Greetings folks

I have a problem that bugs me for years, I never intentionally solved it, sometimes those errors disappears and all USB ports work fine, sometimes they do not. So anyone can help me please, it would be great.

Some of my ports do not work all the time, I cannot identify a specific moment. Inside the Device Manager, Universal Serial Bus controllers, I get 1, 2 or more "Unknown USB Device ( Device Descriptior Request Failed )", sometimes more sometimes less.

CPU: Intel Core i7 3770
Motherboard: AsROCK H77 Pro4/MVP
Windows 10 all available updates downloaded and installed as of today, and everyday. The problem appeared on Win 8 or 7, not sure when. So it's not necessarily Windows 10 specific. I ported it to 10.
Here is what they look like:

Bios is up to date. Chipset drivers updated, various solution tried from googling, I even managed to make all USB ports stop working testing some of these solutions, I had to restore windows from a ghost image I had.

It's like these USB ports remain suspended sometimes.

Any advice on what to try? The most annoying part is that from the frontal USB ports some stop working randomly too.

Thank you

I know that a similar question has been asked before but, not with the last part of the message, (Device Descriptor Request Failed). I get this, in Device Manager, and I have searched for an answer on the net. Also it is a Code 43. I went through my laptop, with an HP Technician this morning, I might add at a cost of 5p/minute, for 30 odd minutes. He has said that because I had gone over to Windows 8.1 and the recovery discs I made will not load, to put back in Windows 8. I have to send the laptop back for re-installing the OS, because Windows 8.1 do not have the update for my problem. Also the R.H. USB socket has a failure ID:0GAPTK-6T7716-MFPWWK-8D1Q03. I personally think that this is all what the problem is. a duff USB. Is this a cop-out???
My question is; has anyone heard of Windows 8.1 having driver WHQL problems?? Very.

Any/all ideas, appreciated.

ps, I only found out the problem with the usb when I tried to download a Mobi file to a Kindle for my wife. The other usb's work OK.

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.

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.

Any suggestions in helping to solve this one would be a great help. Google brings up Intel VIIV for Media Centre but doesn't help me very much.

I've been scouring the newsgroups for answers to the following problem and have tried everything suggested to no avail...

My USB 2.0 Pen Drive was working fine until yesterday. It now shows as unknown device and windows reports that it may not function correctly. It doesn't work at all!

However, I took it to work with me and (on a USB 1.1 PC) it worked well.

When I returned home, I tried again in my PC to no avail. I then tried uninstalling Root Hubs and Controllers and the like from Device Manager as suggested in many newsgroups and the thing sprang back into life. However, as soon as the
Enhanced USB driver is detected, the pen drive vanishes and the 'unknown device' returns.

I've been into safe mode, I've tried to delete the 'VID keys' from the USB section of the registry (which won't delete even though I log in as the administrator) and I've removed all USB devices and then uninstalled all hubs from Devce Manager and let them reinstall themselves.

I now have my Pen Drive working in (I assume) 1.1 mode by means of 'disabling' the 'enhanced host controller'. As soon as it is re-enabled I lose my Pen Drive and return to 'Unknown Device'.

XP says that my 'Enhanced Controller' has no problems.

Please help - everything was fine on Monday and a restore does no good at all. Why can I not delete the VID keys?

Thanks in advance,

I have an external Bluray/DVD drive (ODP1201=S3-B) that works perfectly on Windows 7 but is not recognised by my new laptop which has Windows 8.1 64 bit. Can anybody explain why this is and what I do to get pass it, or is this a problem with Windows 8.1?

The device is listed in Win 7 as "hp bd rom bc 5501h", and the driver is 6.1.7601.17514

I have now tried various USB devices; I have connected a USB 2.0 External Hard Drive and a USB 2.0 Canon Camera both of which work OK, I have also connected a Seagate 1T external drive which is USB 3.0 an that was OK as well (the ports are all USB 3.0 on the laptop hence the reference to the which USB type)

The error message is as follows: "USB Device Not Recognised", When I go in to Device Manager I find two USB error listings, Unknown USB Devise (Device Descriptor Request failed) & Unknown USB Devise (Port Reset Failed)

I have been advised that this error can arise when a drive doesn't receive enough power from the system. The device does have two USB connectors, I have tried using both of them. The power cable going to the powered USB on the laptop and the data going to the adjacent USB (there are a pair of USB sockets on either side of the laptop, the right hand side having the only powered socket).

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.

Hi, I got a Toshiba satellite: A135-S2386 and I have a usb port problem. I got 4 usb ports on this laptop and all four are non-responsive. I tried restoring the laptop to its factory setting and updated the BIOS. I also tried to go into device manager and uninstalling all the usb drivers, restart, and plug in the usb device again. Its weird because when I plug my usb devices in, it still show that the device is connected because the device is charging. The unknown device that I uninstall will reinstall itself automatically and I already run 3 different virus scans from 3 different virus scanners.

I just put in a new Motherboard. An ASUS K8V-MX. It's a Socket 754 with a Athlon 64 processor, an Nvidia video card, 256 MB, A Creative Labs Audigy SE sound card and 2GB's of Kingston memory. I am runnning Windows XP Pro x64 on it.

I just loaded Windows yesterday and I like to get all of my drivers and updates installed first. I also usually check in Device Manager to see if there is ever anything I didn't catch. In my setup, there is a Raid Controller, and since I don't use Raid, I just disabled it. There is also an unknown device, and it's driving me crazy not knowing what it is. I ran this OS on a previous motherboard and it didn't show up there, so I don't know.

I tried to find a driver for it online by clicking on update driver but nothing came back. Then I made the mistake of uninstalling it, only to have it ask me everytime during bootup that there is new hardware and would I like to try to find the driver for it. So I disabled it. But I'm still wondering what it can be.

I would have attached a screenshot of the properties window for the unknown device but I couldnt get it to upload on here. It does mention something about VIA PCI to ISA Bridge. Hope that helps. But I have no ISA slots!

Also is there any way, through the registry or whatever to just completely get rid of these entries in Device manager? The RAID entry and the unknown device?

I recently decided to to a clean install of Windows 7 7127 RC x64. I have been running Windows 7 x86 because even though I have x64 processors, my laptop came with Vista Ultimate x86 installed on it.

After reading about the differences between x86 and x64 systems and the fact that I have 4GB of memory that only came up as 3GB under x86 I thought I would experiment with Windows 7 x64.

My only problem so far is one unknown device under device manger. I originally had three unknown devices but the first two were based on my Nforce PCI system devices which I finally found here:

nforce Vista driver in Others drivers - Windows Vista Downloads

These are the drivers that worked for my AMD based Nforce system :

Nforce Vista drivers downloads - NVIDIA nForce Driver 15.23 WHQL for WinVista64 Vista driver download - Windows Vista Downloads

After installing the drivers I still have that one unknown device listed. I tried to run DriverMax but it only supports Vista x86 not x64. I also tried PC Wizard and a program called "Unknown Devices" that just tells me I have one unknown device...No Duh!!

I tried to identify the device by PCI vendor ID but it doesn't show one. Since the laptop came with everything pre-installed I have no idea what it can be.

These are the only things I can find to identify it.

Recently installed vista ultimate x64 fresh on new hd. I have been using the same copy on my older hd for 8 months.

As far as i'm aware i've installed all newest drivers for hardware.

There are two 'other devices' for which no drivers are installed. One I'm pretty certain is the gameport on my audigy 2 zs platinum pro [location = pci bus 2], which isn't supported in vista. the other one is a mystery [location = 'on Msoft ACPI-Compliant System].

I don't care about the gameport but i'd like to get to the bottom of the second device. The thing is the only thing that makes any sense to me in properties/details is in 'siblings' - it looks exactly like the description in the same properties/details for my cpu [athlon 64 x2 6000+] for which there are already 2 instances in 'processors'.



Could this unknown device have something to do with the cpu and might the fact it's unknown be affecting the computer performance?

I can give further info if required. I've no idea what might be needed!

I have a Dell Dimension 4550 which i bought around 2002 brand new. Everything worked fine for a while until maybe two or three years ago. At the time, i was using all the usb plug ins which included 4 in the back and 2 in the front for different devices. Some of which included three external hard drives. I was trying to organize a number of project by placing them into different drives at the time. Some of my hard drives started to malfunction one by one. Then my usb connections started to malfunction and my computer could or would not recognize the device that was plugged in even though they all are 'plug and play' devices. The funny thing about this problem is by changing the location of the usb plug in sometimes the computer would recognize the device. However this also started to give me major problems SO i bought a usb pci card and thing started to work better as far as using the pci card. Eventually i bought another usb pci card and now i have 8 additional usb slots. One of my biggest concerns is reconnecting my external hard drives but connecting them to the pci cards, my system is recognizing them. Now the issue i am having allot of problems with is my flash drives. trying to connect them to the front two usb ports i get an edit (usb device not recognized - unknown device).

I have a Dell notebook, with what I believe is a USB 1.1 port on it. I recently bought a Microsoft wireless notebook optical mouse. There is no installation CD with it, you are just supposed to plug it in and it should work. Well when I do that, I get an error comes up saying USB device not recognized. When I look at the properties it says "no drivers are installed for this device", and I have the device usage as enabled. I've tried updating the driver and it says I have the most recent updates installed. It comes up as an unknown device as well.

Other things like my printer work in this USB port, so I don't think the port itself is defective. I also plugged the mouse into another computer and it works with no problems. I am running on XP with SP2 installed.

The product specs say it should work on USB 1.1 or 2.0, so I don't think that is the problem either. Any ideas? I've gone through all of the troubleshooting with no luck.

I have a portable hard drive that i attach to my computer via USB.
It has worked fine so far but now when i plug it in the only response i get a message saying "USB device not recognized, one of the devices attached to this computer has malfunctioned....." and under Device Manager in Universal Serial Bus Controller Ican see not 1 but 2 Unknown Devices.

If I uninstall them both, unplug the hard drive from the usb port and do a Scan For Hardware Changes then I will get the message "Unkown Device. Device Driver Software installed successfully" and one unknown device will reappear in the Universal Serial Bus Controller.
Now I wonder: what device is that?? Clicking on properties doesn't really help

Plugging in the usb hard drive will bring again the error message "USB device not recognized....." then "Unknown device. Device driver software installed successfully" and the unknown devices number in Device manager back to 2.

Hello,I recently put together a new computer, and in the process of of installing the USB 3.0 connector from the front of my GX500 case, I either bent numerous pins on the motherboard USB 3.0 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 3.0 functionality, I bought a USB 3.0 -> 2.0 adapter cable, connected one end to the connector on the front of the case and the other end into the USB 2.0/1.1 header on the motherboard. Unfortunately, when Windows 7 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 2.0/1.1 ports via the adapter cable.  I've tried both USB 2.0/1.1 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 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 co...

Do you happen to have a spare machine that you can test the adapter with?  Just as a precaution in case the adapter is faulty.

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.

You may try one thing ... Right click on my computer and choose "manage". It will open the computer management window. In the left hand pane, click on "device manager", it will list all the devices attached with your computer in the right hand pane. Expand "display adapters" ... right click on nvidia, and select "update driver software".

Recently I upgraded my windows home premium o/s to win 8 without much fanfare. After the installation was complete I notice under the Device Manager , 1 Device Unknown is shown. This means 1 device has no driver.

Can anyone tell me:

1. How I can identify this missing driver?
2. Where I can locate this driver?

My laptop is a HP.

I've had my windows 8 pro installed for about a month or so now. Whenever I access device manager, it tells me there is one device that's an "unknown device". I've updated drivers, done driver scans online to figure out what driver this is. Everything works perfectly!

Is there some program/ online utility that can accurately tell me what driver this can possibly be?

thanks in advance!

ok so this seems to be a little different than most unknown device problems
all of my devices work fine

i keep getting pop ups in the task bar telling me new hardware has been found
then it pops up unknown USB device not recognized
sure enough when i go into my device manager there is an unknown device attached to the usb controller
now it seems to come and go and if i watch the device manager for a couple minutes you can see it connecting then disappearing 4, 5, 6 times in a row

it first started doing this when i had a couple usb devices plugged in (external hd, mouse, printer)
since then i have gone as far as doing a fresh XP install and not connecting any usb devices at all
but sure enough after a short while new hardware pop up and followed by unknown usb device not recognized
i check device manager and there it is
it also seems to be sitting in the registry at vid_0000&pid_0000
i can delete the registry and i can uninstall the device but it just keeps coming back

now none of this seems to be causing a problem
and all of my devices work when plugged in
but its an annoyance to have the new hardware and unknown device balloon tip pop up
i know i could disable those but clearly there is something wrong and id like to get to the bottom of it rather than just hide it

the very first time that it happened was right after i unplugged a storage device from the front of my case (rather violently)
at first i thought maybe i damaged the pins when i pulled it out
but the devic... Read more

Have you checked in Device Manager for yellow alerts?

Does the message contain the words "unknown device", or is it a device you don't recognise?

I would recommend running some malware scans in case this is related to a virus infection:-

Your Device Manager doesn't appear to have any devices with problems, so it's possibly a "false positive" from the Lenovo Solution Center.

Are all of the devices in your computer working okay?

At a guess, you may need to install the nVidia chipset drivers for your notebook.

HP/Compaq has no Win7 drivers for it, but the Vista drivers may work:

Select software and drivers*

Do you get (from the Win7 install, or Windows Update) good drivers for the notebook's graphics, sound, etc.? It'd be nice if the Windows 7 installer included every conceivable driver, but it may not.

Under Device Manager , Other Devices, it indicates an unknown device. It would load each time I started Windows 98 S.E. but was never able to find a correct driver. I disabled it. Is there some way to determine what this unknown device is?

Thank you

A:unknown device

Not really, no.

You can do it by process of elimination if you really want to... take out all your add on cards (modem, sound, etc) and put them back in one at a time to see which one it is.

Not sure it's worth doing that though.

Hi all. Since installing Windows7 64bit, I have an 'unknown device' (see pic). I've not installed any new hardware except 4GB RAM but that's been recognised by Windows already. Any way I can find out about this device so's to get rid of the warning triangle?

Many thanks.

A:Unknown Device

Maybe win 7 doesnt have a driver for whatever that is. You could try unplugging usb devices (safely) and checking to see if that usb port is referenced to a specific piece of hardware. I had an external usb HD that was no problem in vista but there wasnt a driver for it in win 7 beta. After driver install no problem. Just guessing though

Good Luck
