    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.

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

    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.

  4. 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.

  5. 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.

    1. After a day or two trying to fix this. I manged to borrow a cable from my sis who came by for dinner. IT WAS LE DANG FAULTY CABLE… There goes my $31… At least I think I still get “lightning” charging from it…

  6. I’ve been trying to factory reset an ipad but it has been coming up with the error described on the web page. although when i use my ipod it works normally. Does this mean theres something wrong with the ipad then because none of these fixes, fixed it.

    I have three different USB-C cables from two different mfgs and none of them will connect without a "unknown USB device" unless the USB cable phone connector is turned 180 degrees!!!!!

    I realize USB C is supposed to work in either direction, but my Nexus 6P phone connector must have gone bad.

    I tried different Windows 10 PCs, OEM drivers, Android Studio drivers. Microsoft drivers, power settings, rebooting the PC, rebooting the phone, and three different cables before I came across the magic bullet and tried plugging in the cable in a different orientation. I didn't see this solution on any of the dozen pages around this issue. All three cables work if turned around.
