[Robin <1382302@xxxxxxxxxxxxxxxxxx>]

The description in #5 is not a fix, but rather a hack, which will have to be repeated for every kernel update. A true fix would involve:
a) amending the btusb file
b) including the fully BT capable firmware in a package

If only a) is done, that would be a big improvement!

Please note that 14.04 LTS will be using the 3.13.0 kernel until 2019,
so this bug needs a robust fix!

Thanks to redfox for getting to the bottom of it!
