Windows 10: Qualcomm QCA9377 Bluetooth problems

Windows has stopped this device because it has reported problems. Code 43


Windows disabled the driver.


I've installed the latest driver and it didn't fix the problem

Qualcomm QCA9377

Not just about old computers, on *116, I was losing WIFI intermittently, the network would disconnect. Reverting to *113 was the only solution. Not to mention the Sandbox startup issue.

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?
