[Bug 962082] Re: Profiles that require duplex audio like Head Set (HSP) and Hands Free (HFP) do not work on machines with Broadcom BCM20702A0 Bluetooth chips

[Tim Abell]

For the record I also have an identical issue with a much older D-Link
DBT-122 dongle

tim at atom:~% lsusb | grep DBT
Bus 001 Device 009: ID 07d1:f101 D-Link System DBT-122 Bluetooth

bluetooth-adapter

This apparently is also a broadcom chip.
