If you have purchased a UGREEN Bluetooth 5.3 USB adapter (common models include the CM492 , CM591 , or the generic "long-range" adapters), getting it running usually requires a specific driver. Windows 10 and 11 often try to install a generic driver automatically, but this frequently results in errors like "Bluetooth Radio cannot start" or the device showing up as an "Unknown Device."
