Support for 0bda:8771, ala RTL8761B, seems not given.
So far as I interpret this is it supposed to be in the kernel?
When I activate the Bluetooth Device Wizard does it not see any available devices.
Tested it with my phone. Also tested it with my new BT amplifier. The phone sees the amplifier.
Also doesn't work with other Linux distributions.
