It's amazing! Yes, you are right! In my case, simply moving it to /lib/firmware
made the last 3 bytes of BD address change from 00-00-00 to 00:1F:AC.

It's so unreasonable!

In my case btattach runs (although it doesn't fork to background like the
tutorial suggested). If I enable bluetooth ($ sudo hciconfig hci1 up) I can
scan devices.

To connect and pair devices, the bluetooth shipped with Ubuntu 15.10 won't
work. blueman (launch with blueman-manager)'s "add new device" wizard works for
me.

It's the first time I got bluetooth mouse working since I bought the computer
one year ago.
