USB Device Not Recognized. Device Descriptor Request Failed

The first thing I did was check my USB drivers, but there is not a problem with them. After that, I checked USB port fearing it might be a hardware problem but again no problem found because other devices are working perfectly like my keyboard, mouse etc. The problem occurs only when I insert my hard disk, so I thought there must be an issue with my hard disk but again no problem found as it was working perfectly in another laptop. Now i was seriously worried because after checking everything this must be a “Motherboard” issue but i was seriously relived when i found out that the problem is with the Fast startup and USB Selective Suspend Settings are enabled. Let’s see how to fix Unknown USB Device problem.

    The Alternate soltution i found for this is either try to us the USB drive on different version of of USB port like USB 3.0, I had the same issue i fixed it by using the USB 3.0 port of other PC

    Mine’s working! I was going to try out Method 5, but I did this one a little bit different. I update the driver (the one with exclamation mark in a yellow triangle) with Generic USB Hub. Then I uninstall it for some stupid reason. Now the driver dissappears so I think reconnecting my USB device will make it appear again. But after reconnecting, it installs a driver automatically, and now my WIndows recognizes it! One more thing, I’m really sure this is also because I’ve disabled Fast Startup and USB selective suspend setting.

    Method 4: Change the USB Selective Suspend Settings
    This solved the issue for my ” Xbox 360 Wireless Receiver for Windows ” using Windows 8.1
    Thanks!!!

    First my device was shown as an ” Unknown USB Device (Device Descriptor Request Failed) ” under the ” Universal Serial Bus controllers ” section.

    After applying method 4 I uninstalled the device from device manger and unplugged the receiver from the USB port.

    After that I shut down the PC, waited for a bit and started again.

    Now the device was displayed in the Device Manger again as ” Unkown Device ” under the ” Other devices ” section. It worked again after installing the receiver drivers on the Unkown Device.

    I’ve had this issue, followed this troubleshooter, still getting the same problem, I uninstalled the software for the USB device, then tried Troubleshoot Compatibility (right click the .exe file), selected Try recommended settings, after a second it comes up with the recommended setting, select Test the program and now it works.

    So I’ve tried Method 2, I’m still getting “USB device not recognised”. So i can’t get my iPhone 6 to be recognised.

    • My windows is up to date, I’ve spammed clicked the “check of updates” and nothing pops up.
    • My iPhone 6 is up to date, iOS 10.2.1 (13/04/17)
    • iCloud Photos still able to be seen in “My Computer” that’s a plus.
    • I did not receive “Trust this Computer” on my iPhone at all after plugging in. – I’ve gone to general settings and did some resets, still didn’t work.
    • I’ve re-installed iTunes 2 times. as well as other apple related programmes like ?Bonjour?, etc..
    • I’ve updated my BIOS and Drivers most probably.
    • I’ve tried multiple USB ports on my desktop as well as my monitor.

    I was still able to sync a few days ago, now it’s gone haywire. I don’t have any idea what’s going on.
