Comment 33 for bug 1576559

Fresh install of Ubuntu 20.04 with a TT BH060 (TaoTronics):

        Modalias: bluetooth:v000ApFFFFdFFFF

Also, kernel messages (hundreds):
[149342.549626] Bluetooth: hci0: SCO packet for unknown connection handle 0
[149342.549628] Bluetooth: hci0: SCO packet for unknown connection handle 12289

Switching to HSP/HFP just deactivates it completely. Only A2DP works as expected.
