Hello,
I have an Asus X571GT, and for the past couple of weeks, I've been having problems with my Bluetooth randomly shutting off.
I've tried everything. Uninstalling it and reinstalling the Intel drivers, and sometimes the mouse wouldn't work upon a reboot, and sometimes it would...and when it did, it would last a couple hours to a couple days before the Bluetooth randomly disappeared again. Same thing with reinstalling the Asus drivers.
Everything is up to date. Nothing could fix it.
But then I remembered when this problem originally happened a month ago, in Device Manager under USB Controllers, was this "unknown usb device descriptor request failed"
I restarted my research all over and realized that A LOT of people have this same problem, and that this "unknown usb device descriptor request failed" is what's causing the Bluetooth on most computers to randomly disappear.
I uninstalled this random USB device descriptor and upon a reboot, the mouse (so far) is working.
Anybody knows what this "unknown usb device descriptor request failed" is, and more importantly, does anybody have more a a permeant fix?
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
Meaning what exactly?
The only things I have plugged into my computer are...
Does this mean the for #1 that the Mouse adapter is corrupt (ie buying a new mouse)? Or the system reading anything plugged into the mouse adapter is corrupted?

Unfortunately, I cannot diagnose this problem distantly.
Sometimes a device may start working successfully but then become faulty.
Note, some devices may be connected internally, this depends of computer manufacturer.
You may open Device manager, disconnect devices one by one and see when this faulty device will disappear.
Hi Andrew,
My name is Igor, it's a pleasure for me to help others and I'll do all my best to help you.
Sorry if I disappoint you, but this message means some USB device is faulty and does not respond correctly to identification request.
The permanent fix is to disconnect this device or to repair it.
