uellue, if it works in Windows, then it clearly would be a Ubuntu versus
a hardware fault. As well, if you have to play all these games of
pulling out a battery, rebooting, etc. to get it to work in Ubuntu, it
would appear to be some wonky timing issue.

Despite this, in order to further narrow the offending package (ex. is
this an issue occurring with a specific kernel, firmware, and userspace
combination) would it be possible for you to create another partition,
install Precise 12.04.1 via http://old-
releases.ubuntu.com/releases/12.04.1/ubuntu-12.04.1-desktop-amd64.iso ,
and fully update (be sure not to upgrade the kernel as per the
enablement stack upgrade outlined in
https://wiki.ubuntu.com/Kernel/LTSEnablementStack), and advise if the
bluetooth still works?

If so, could you please install just the firmware from Trusty to see if
it still works?

Title:
  Bluetooth: can't load firmware, may not work correctly

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Bluetooth does not work. The tray icon appears, but none of the functionality is available. Probable cause:
