Recently I attempted to connect to an existing paired connection to my phone via bluetooth. I have never had this problem before, yet suddenly Bluetooth is missing. There is no longer an icon in the taskbar, the setting in "PC and Devices" is missing, and there appears to not be a driver installed, rather, an ""Unknown USB Device (Device Descriptor Request Failed)" appears in my devices instead. I have taken many steps to attempt and fix this, such as:
Everything else in the PC functions perfectly. Any help is appreciated
- manually starting Bluetooth services from services.msc
- uninstalling the "Unknown Device" driver, then attempting to let Windows reinstall
- downloaded the driver software from Lenovo for the Bluetooth adapter, installed it manually restarted
- take a system restore created yesterday and revert back to it
Everything else in the PC functions perfectly. Any help is appreciated
