It seems that this has been a known issue for all Broadcom BT devices in
standard Ubuntu and the issue can be fixed if we simply pack the same
solution (brcm installer) into standard Ubuntu. Or users are advised to
refer to the instructions given in http://askubuntu.com/questions/533043
/bluetooth-not-working-on-ubuntu-14-04-with-dell-inspiron-15-3521 and
fix it by themselves.

Title:
  Broadcom Bluetooth [413c:8143] does not work at all

Status in HWE Next Project:
  Won't Fix
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  CID: 201307-13942 Dell Latitude E5540

  The Bluetooth can't find any devices.
  Error message could be found in dmesg:
  [   98.149145] Bluetooth: can't load firmware, may not work correctly

  Note that sometimes it works, but if you disable and re-enable it with
  the wifi slider (let it reload the firmware), it will stop working.

  Steps:
  1. Install 14.04.1 + update (3.13.0-37) + proprietary Broadcom driver
  2. Try to pair with any other Bluetooth device.

  Expected result:
  * Bluetooth works well as expected.

  Actual result:
  * Nothing can be detected.
