I was just working happily when my Microsoft Bluetooth Mouse just suddenly stopped working.

The Bluetooth settings page says "Bluetooth is turned off" and there are no options on the settings page or the system tray to turn Bluetooth on.

The Device Manager now has "Unknown USB device - device descriptor request failed" where it did not before.

Other devices all seem to be working fine - USB devices plugged in are being recognized and work properly. Only BT seems to be broken.

I've tried:

uninstalling the device and rebooting

installing the latest updated chipset drivers from the dell website

windows updates

pretty much all of the advice here: http ://troubleshooter.xyz/wiki/fix-usb-device-not-recognized-device-descriptor-request-failed

Any other ideas?

Thanks
