Hi there.

I'm running Ubuntu Trusty Tahr (14.04) 64bit and I'm affected by this
bug.

By following the instructions here (especially comment #101 by Chris
(poser) on 2013-09-15), I was able to get HSP/HFP working on my system.
I realized something was broken when I tried to pair my Laptop with a
PLCM VS500 (Voice Station conference phone) and couldn't.  I was
especially angry when a friend running a MacBook Air (Grrr, don't get me
started...) was able to immediately pair and use the headset.  My anger
brought me here and I can say all is well.

  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.
