How do I read input from Oculus & Vive controllers?

I just own a Oculus Rift but would like to make sure I can get input from the Vives controllers as well. Both devices have similar buttons. So I can't test it on the Vive. But even for the Rift reading the inputs is not working for me. The following code just shows always 0 in the console, it doesn't look like I can actually get the input back.

 void Update () {
         float move = Input.GetAxis("Oculus_GearVR_RThumbstickY");
         Debug.Log(move);
 }

So what am I doing wrong?
