I have looked at some other answers already, none of them seemed applicable or fixed anything.
I have USB Bluetooth on 15.10. It used to work fine. I went to pair my headphones today and noticed I couldn't turn Bluetooth on.

So it seems the driver or firmware for it is missing for some reason. How do I reinstall it? Is there an apt package that takes care of this?
I have tried find
/locate
on BCM20702A1-0a5c-21e8.hcd
and wildcard variations to see if maybe it was just in the wrong place, and that does not seem to be the case - I believe it was deleted at some point, somehow.
UPDATES
As per P.H. Lin and Jeremy31's comments:
- Installing the firmware from the other thread did not fix my problem, and
lsusb
no longer detected a BT unit.hciconfig -a
did not return any output. - I removed the firmware file (
*.hcd
) rebooted and my BT unit appeared again onlbusb
, with the result ofsudo hciconfig -a
being:
$ sudo hciconfig -a

However the unit still does not "work" so I am back where I started it would seem.
