This seems to be a fairly common issue with the Reverb G2, I've come across 3 games so far out of the dozen or so I've played where I can't move, because it detects my controllers as Vive controllers, and the G2 controllers don't have touchpads (they are more like Rift controllers)
Pressing the sticks does nothing.
Is there a way to force a different controller style so I can play?
