oxygen 25 mk4

Hey. I’ve messed around with the oxygen 25 and cubase for the first time today and i can’t get the knobs from my m-audio oxygen 25 working. Only the c5 seems to work, and only for panning when I’m on a audio track. Are you supposed to set the buttons up manually or is the oxygen just not working for cubase 8? I can see the input in cubase when i turn the knob, it just doesn’t do anything.
