Logitech G27 not calibrating correctly and not recognizing pedals

Hey guys,

So I've been trying to fix my G27 wheel for a little while now but to no avail.

Basically the problem I'm having is it won't calibrate the wheel to the center and won't recognize my shifter, clutch or brake. The calibrating issue will only occur when I'm in game but the shifter and pedals are all the time.

Any Ideas?

Cheers
