Qualcomm' Atheros'QCA9377' Bluetooth '4.1 Driver, 10.0.0.265 for,Windows.',10 hidden network drivers ,Qualcomm. I am out of options that I know of to troubleshoot this as Bluetooth isn't showing up no matter what I do.➝➝➝ Qualcomm Atheros QCA9377 Bluetooth 4.1 Driver 10.0.0.265 for Windows 10 The Windows 'Bluetooth Support Service' is running and can start/stop successfully - it is also set to Automatic startup.Īirplane mode is not enabled and toggling it on/off has no effect on the Bluetooth situation, though it does turn WiFi on/off as it should. I have no USB devices connected to the system so it is unclear what this unknown USB device is above - perhaps it could be the Bluetooth adapter but I don't seem to be able to get that unknown device to find a driver update online. The only possibly suspicious thing to note in Device Manager is a device under: Universal Serial Bus controllers > Unknown USB Device (Device Descriptor Request Failed). However, WiFi is working fine which would suggest that the device itself is presumably ok and still present. It is as if the Bluetooth device no longer exists on the system. I have run the 'Scan for hardware changes' in Device Manager but this does not detect anything new. Upon reinstalling the driver Bluetooth is no longer listed anywhere in Device Manager. I proceeded to uninstall and reinstall the Atheros QCA9377 driver as available from the Asus website ( ). I checked in Device Manager and the Bluetooth devices were greyed out though they were not disabled (had to enable 'Show hidden devices' in Device Manager to see the Bluetooth section in the device tree). The Bluetooth suddenly stopped working this morning and as a result the wireless mouse no longer works (this is how I knew Bluetooth stopped as I was using the machine at the time). I have an Asus T102HA which has an integrated Qualcomm Atheros QCA9377 WiFi+Bluetooth adapter.
