Windows 10: Comfast USB Bluetooth and WiFi adapter stopped working after updating drivers and fixing...

The USB adapter in question is Comfast CF-732B, little blue usb thing. I had plugged it onto the blue ports at the back of my PC and got it working on the first try. My PC has windows 10, haven't bought it and I don't plan on doing so. I followed this tutorial to the second step where I downloaded this d

Hello Everyone

Problem with Hama Bluetooth USB-adapter drivers

Here is the answer I received from Hama support:

 

Bluetooth Stopped Working in Windows 10 (Qualcomm Atheros QCA9377)

I have an Asus T102HA which has an integrated Qualcomm Atheros QCA9377 WiFi+Bluetooth adapter. 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 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).

I proceeded to uninstall and reinstall the Atheros QCA9377 driver as available from the Asus website (https://www.asus.com/uk/support/Download/3/919/0/1/EKnJ4vWdmuN3xLti/45/). Upon reinstalling the driver Bluetooth is no longer listed anywhere in Device Manager.

I have run the "Scan for hardware changes" in Device Manager but this does not detect anything new.

It is as if the Bluetooth device no longer exists on the system. However, WiFi is working fine which would suggest that the device itself is presumably ok and still present.

The only possibly suspicious thing to note in Device Manager is a device under:

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 Windows 'Bluetooth Support Service' is running and can start/stop successfully - it is also set to Automatic startup.

Airplane 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 am out of options that I know of to troubleshoot this as Bluetooth isn't showing up no matter what I do.

How can I troubleshoot further and get the Bluetooth adapter reinstalled properly?
