Version 4.1.1 (grabbed it from github with manual install on raspbian). RPi model B.
Yeah, tried both removing and reinstalling. No luck with that. Maybe github version of the driver is a bit outdated..? product and vendor ID's are correct, but something is just not working with 4.4 kernel.

@igmothemagus this. Both controllers are not the same- the architecture of the new controller was moved to bluetooth because it was a simpler and faster band than the one they were apparently using for the original. There was a distinct attempt to brand this new controller as "Bluetooth", even at their E3 conference.

Of course, that didn't stop them from attempting to keep it as exclusive to their platform as they possibly could. The Linux kids are having all sorts of problems using it wireless via Bluetooth on their PC's. It's a mess.
