Installed 4.1.2-040102 kernel on Ubuntu 14.04 and I was able to compile and install the rtbth driver with dkms. The same thing happens again: can't pair with any device.
So, I think that the last Ubuntu release on which it works flawlessly is 13.10. Maybe it works with a newer Ubuntu release but it's veeeeeeeeeeery unlikely to happen.
