V-Studio 20 and X1

hi guys~!

I have purchased my V-Studio 20 recently and I need some help.

How do I make this devise work in X1 producer as it works as in Guitar Track4.

I mean, X1 producer recognize the device and it works as interface and everything, but I somehow can't get my other buttons work(play, record track select, etc...).
