Title:
  Broadcom bluetooth device BCM20702A0 [0a5c:21e8] not supported

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I have a IOGEAR Bluetooth 4.0 USB Micro Adapter (GBU521) which cannot
  audio sink with my bluetooth headphones (Kinovio BTH-220).  Headphones
  can be detected and pair, but audio sink or mic input doesn't work.
  Blueman manager gives the error "Connection Failed: Stream Setup
  Failed.  It used to work in the LTS Ubuntu version 12.04 but now no
  longer does with a kernel update.   This Broadcom chip BCM20702A0 has
  had many bug reports on it on launchpad which have been fixed in
  previous releases.  There is a lot of info in these previous bug
  reports that is useful for people diagnosing and solving the problem,
  although I did not understand most of it.  From reading them, I
  believe the problem comes down to vendor ID support or the issue of
  the adapter needing to load a special firmware.
