Bug Description

0b05:17cb ASUSTek Computer, Inc. Broadcom BCM20702A0 Bluetooth

I have a USB Bluetooth dongle from ASUS based on the fairly common Broadcom BCM20702A0 chipset.

I can pair bluetooth audio device to this and have tried a JabraSpeak 510 Bluetooth Speaker/Mic and a Plantronics Voyager Legend headset.

I can pair both successfully, however, they DO NOT WORK in HSP/HFP mode, I can only use them for audio output in A2DP Sync mode.

I have tested this on both the GA 4.15 kernel and the HWE 5.0 kernel with the same issue on each. HSP/HFP does not work.
