So about two days ago Bluetooth completely disappeared from Windows. When I checked device manager, there was an exclamation mark under Universal Serial Bus controllers on an item "Unknown USB Device (Device Descriptor Request Failed). I eventually fixed it and got bluetooth working again but I can't remember how, I do remember reinstalling the Bluetooth driver but I had to do more than just that. This problem occurred again last night and I was unable to fix it. I checked Event Viewer and it appeared that there were some other problems with Windows. Explorer.exe had been crashing hourly as well so I decided I would fix it all by reinstalling Windows. However, after reinstalling Windows 10 as well as all my drivers(including Bluetooth), the error persists. How can I permanently fix this problem?
