[Kyle Manna <1065400@xxxxxxxxxxxxxxxxxx>]

I'm running 3.11.0-7 Saucy kernel on Raring and the firmware gets
loaded, but it doesn't enable A2DP.  Seems that the firmware loader is
working, but I have the wrong firmware?

I have an Iogear GBU521 / 0a5c:21e8  like Elijah.  I fetched the windows
driver from http://www.iogear.com/support/dm/driver/GBU521 and used
hex2hcd on firmware BCM20702A1_001.002.014.0889.0896.hex from the
bcbtums-win8x64-brcm.inf from my vid:pid.

/proc/version:
Linux version 3.11.0-7-generic (root@core) (gcc version 4.7.3 (Ubuntu/Linaro 4.7.3-1ubuntu1) ) #14 SMP Mon Sep 16 22:03:29 PDT 2013

  Support for loading Broadcom bluetooth firmware

Bug description:
  Broadcom bluetooth chips require a tool called patchram uploader [1]
  to load firmware. This applies to at least BCM20702 and BCM43142.
  Although some of the devices have an OTPROM that contains required
  firmware, but it is found that these devices would not have HFP/HSP
  support unless a upgraded firmware is loaded via patchram uploader.

  This tool requires hci device to do the firmware loading, but this may
  cause some race condition between patchram tool and bluetoothd or
  something that also works on hci interface.

  Also it needs some hooks to make firmware loads after bootup, s3,  s4,
  rfkill, and device hotplug events. Implement this loader in kernel
  module would make things more easier.
