[ubuntu] Bluetooth keyboard dock not working on 16.04 LTS

Hi guys,

I have an Asus Transformer Book t300 chi, which has a separated bluetooth keyboard dock and trackpad. It works out of the box with Ubuntu 14.04. I tried the version after that, I think 14.10, and the bluetooth keyboard stopped working
I asked this on the forums too, but decided to wait for the next LTS to see if the problem would be solved.

Now I tried the 16.04 live usb and they bluetooth still doesnt work! This is really strange as this used to work very well.

I'm prepared to supply any details needed to fix this, thanks!
