[Solved] Unknown USB Device (Device Descriptor Request Failed) for Windows 10

By Camilla Mo in Common Errors
If your external USB device is not recognized by Windows 10, and meet Unknown USB Device (Device Descriptor Request Failed) error in Device Manager, use solutions here to troubleshoot and fix the error. 

As you have noticed, the USB Device in Device Manager has a yellow triangle on it:


The error can be caused by hardware issues. So first, follow below simple instructions to do the troubleshooting.

1.  Try the device on a different USB port. This will figure out if problem is caused by a broken port. 

2. Connect the device to another PC. This will figure out if the external device has problem.

If there is no problem with the USB port and the device, read on and try the following methods. You can start at the top of the list and work your way down.

Method 1: Remove the Power Supply
Method 2: Uninstall the USB Driver in Device Manager
Method 3 : Update the USB Driver
Method 4: Disable Fast Startup
Method 5: Change the USB Selective Suspend Settings

Method 1: Remove the Power Supply

This method will fix the problem magically if the problem is caused by Power Supply.

1. Remove the Power Supply plug from PC.

2. Restart the PC and connect the device to the USB port.

3. After that, plug in the Power Supply. 

Method 2: Uninstall the USB Driver in Device Manager

Follow these steps:

1. Open Device Manager and expand category Universal Serial Bus Controllers and locate the USB device which is not being recognized by Windows.

2. Right-click on the device and select Uninstall from the context menu.

3. After finishing the uninstallation, restart your PC then Windows will reinstall the device automatically.

Method 3 : Update the USB Driver

The problem can be caused by faulty USB driver. In this case, updating driver would fix the problem. 

If you’re not confident playing around with drivers manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

1. Download and install Driver Easy.

2. Run Driver Easy and click Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3. Click the Update button next to a flagged USB driver to automatically download and install the correct version of this driver (you can do this with the FREE version). Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

Method 4: Disable Fast Startup

If Windows is booting quickly,the external device may not be detected before the boot is completed, then the problem will occur. In this case, disabling the fast boot option in Power Options can resolve the problem.

1. Press Win+R (Windows logo key and R key) at the same time. A Run dialog box will appear.

2. Type control in the run box and click OK button. This is to open Control Panel.

3. View by Large Icons and click on Power Options.

4. Select Choose what the power buttons do in left pane.

5. Click on Change settings that are corrently unavailable.

6. Under Shutdown settings, uncheck the box next to Turn on fast startup (recommended). Then click on Save changes button.

7. Restart your PC and see if the problem resolves. Note your PC will boot a little slower. 

Method 5: Change the USB Selective Suspend Settings

Follow these steps:

1. In Power Options, click on Show additional plans. (If you tried Method 2, you must know how to go to Power Options. If not, go back to Method 2 and refer the steps to open Power Options.)

2. Click Change settings that are currently unavailable.

3. Select High performance and click on Change plan settings

4.  Click on Change advanced power settings

5. Click on Change settings that are currently unavailable.

6. Locate USB settings and expand it.

7. Expand USB selective suspend setting. Disable both On battery and Plugged in settings.

8. Click Apply button and restart your computer.

    Hello. HP BC000. Win10. Had the same problem. Tried everything. Though my mouse worked in all other notebook pors and none of my devices worked in this one port. So i uninstalled USB hub, rebooted and it started working. But it worked for a few minutes only untill I replugged my mouse. Then it happened again. Then i uninstalled USB bub again. For now it’s working but I do believe only untill I replug my mouse again. Any ideas?

  • Amoraluv

    thank you!! turning off my psu worked to solve the problem.

  • james forecci

    none worked for usb mouse

  • Ulan Murzatayev

    In my case I turned off the laptop,took the battery out, waited for a minute, then turned it on and the problem was solved.

    Thanks for the article! I think Method 1 is a variation of what I did.

  • Brenden Nichols

    If any of you had success with a particular method either in this post or through your own knowledge, what worked for you?

    • yujiyuji

      i just disable and then enable the device while it plugged

      • Brenden Nichols

        I solved the problem a few days ago by using a different USB cord to charge my mobile device.

  • Mark Kornak

    The problem could also be you have an older PC where the BIOS has an incompatibility with Windows 10. Go into the BIOS and disable “Wake on USB” for Keyboard and Mouse. This cleared things up for me.

  • Arthour

    I found that going into Device Manager and ‘Uninstalling the device’, and then plugging in the USB I had been using at the time, before telling Device Manager to scan for Hardware changes in the USB ports fixed this problem. I think it was becuase I’ve had this USB reciver for a mouse plugged into it for so long, that when I removed it from the port, the computer didn’t recognise that it’d been removed and got caught in a loop trying to identify a device that wasn’t there anymore, locking the USB port down. Works fine now.

    • This actually worked for a portable WD USB drive connected to the USB 3.0 port. When trying to plug it into the USB 3.0 it wouldn’t be recognized but would in the USB 2.0 port. Once I uninstalled the “Unknown USB Device (Device Descriptor Request Failed)” and then connected the portable USB drive the drive was recognized in the USB 3.0 port. *This seemed to be connected to the USB Root Hub (USB 3.0) I think.

    • Jlbenc

      When a comment for a [SOLVED] issues actually solves your problem… 🙂


    • fahad

      can you explain it briefly

    • remm

      thanks, it works for me

  • Sumdger

    none worked for me either…… 🙁

    • Jlbenc

      Check Arthur’s comment above. Just had to do “Uninstall..”, take it out before re scanning and then pugging it in again. Hope this helps.

      • Brenden Nichols

        I’ve tried everything, including the comment above, yet nothing has been successful thus far.

  • kay

    i was tried method 2, i didnt click uninstall but i clicked update driver software instead…. and its work…my bluetooth is back…thnks…

  • none of these methods worked for me for the USB microphone I was trying to get to work

  • philthetird

    none of the methods worked

  • Daniel

    For me the trick of powering off the power supply did the trick, indeed I just turned off the nobreak and waited a minute

    • Lebohang Don-Lebzotic Maphatso

      How did you do that?

  • Telboy

    Thank you so much for this guys. I have been messing about with this problem for about 2 months now and thankfully found your page. Method 2 was the one that sorted things for me. It always recurs when there is a software update but at least i know how to fix it now thanks to you.

    • Telboy

      Forgot to say in my last post i have also found that not letting your laptop “Sleep” also helps. I changed all my power settings to “Hibernate” and it’s working for me anyway.

  • Gary

    Having the same problem with a Razer Deathadder Chroma. Works for about an hour or so on the first use of the day and then stops and wont work at all. This mouse works on a different computer. A different mouse works on this computer. Tried everything on this list and more. I get 2 different error messages “Set Address Failed” and “Device Descriptor Request Failed”. Doesn’t make any sense as the mouse works for a while and then stops. Any help would be appreciated!

    • James Winder

      Did you solve this? I’m having the same problem with a Vortex Core keyboard and it’s driving me insane.

  • Eli

    I’ve tried everything here and my mouse is still not recognized. Works fine on other computers.

  • Saroj Shrestha

    Worth reading. Very well explained in detail

  • Justin

    I had this…. Same sort of story…. My equipment is a Sandisk USB Micro SD adapter (SanDisk MobileMate Duo USB 2.0 Card Reader TransFlash Adapter micro SD SDHC SDXC part number SDDRK-121) and 128GB Samsung EVO Micro SD card. It is attached to my Lenovo MIIX 310 by a micro USB OTG cable because the adapter won’t work in the regular full size ports as the machine does not power the device. The adapter with card in was clearly seen in other equipment. Turns out it was the OTG cable that was causing the problem. I took it back to the shop with my tablet. I showed them the error and then we swapped the OTG cable for a new one and… BAM!!! Instant fix!!! So I suggest if you are using that sort of equipment you check that as a potential problem early in the investigation. Good luck all.

  • Robert

    on my USB 2terrabite mass storage the problem was simply
    using a different type of cable..
    i used 1 normal cable that1 did not work it was about 1 meter in size

    then i tryd 1 with that round shape thingy
    cable> [computer] USB———(==)–miniUSB [massstorage]

    from google i learned its this
    >ferrite bead or a choke.

    hope it helps you to

  • Bruce

    Had this problem with a Bakker Elkhuizen keyboard.
    Combining 2 things worked for me:
    -USB selective suspend setting >disabled
    -uninstall driver in device manager

    after reboot, keyboard worked properly

  • steve

    My xbox 360 wireless reciever gives this error no matter what is try. Could it be just broken?

    • Matt

      I have to do this on every PC I plug the XBOX wireless reciever into, everytime:
      Form Device Manager, update driver of unknown device.
      Select ‘Browse my computer..
      Select ‘Let me pick….’
      Scroll down and pick XBOX 360 Peripherals
      Select the the appropriate driver.
      ignore the warning.
      Annoying, but always works.

  • otavio

    Thanks fella!
    My XPS 13 wasn’t recognizing BT anymore. I’ve been hibernating it many times lately and pairing through many devices. I just took the Power adapter out and turned it off and on again and my BT is back!

  • electroFy

    Super! Thanks.

  • Jeff Headley

    thank you so very very much for this post. i had been on chat with 2 different HP reps and a microsoft rep to fix an issue i was having connecting a bluetooth device to my computer. i noticed in device manager i was getting the same unknown device error. i uninstalled it and changed the restart setting and miraculously it worked! thank you again.

  • J_Newton

    Very useful!

    All of a sudden none of my external USB devices would connect via USB anymore. Just like that. I followed your advice and uninstalled the faulty USB device in the manager, restarted Windows, plugged in my phone and my HDD and everything started working again.

    I was about to start messing around with driver updates and setups but this simple solution saved me a lot of time. Thank you!

  • TheMCMan

    using a different usb port did it for me on my Nexus 9

  • Mostaq

  • Vic

    Thank you. The pull power – reboot and power the disk up again worked for me. Well, for now at least.
