I have the bluetooth plugable adapter on two computers running Debian Jessie with kernel 3.16.0-4. Devices such as phone and mouse work well. Bluetooth head phones pair and connect, but the connection is lost immediately. This may be a firmware problem. The following shows the firmware doesn’t load even if it seems to be in the right place.
arl@strider-a:~$ dmesg | grep blue
[5.865894] bluetooth hci0: firmware: failed to load brcm/BCM20702A0-0a5c-21e8.hcd (-2)
[5.869656] bluetooth hci0: Direct firmware load failed with error -2
[5.869660] bluetooth hci0: Falling back to user helper
arl@strider-a:~$ ls /lib/firmware/*.hcd
Is there any thing I can do to fix this?
