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?
