Oculus Home starts automatically?


so, right now i only own a Vive (my DK1 doesnt count :wink: ). I built my first shipping version of my game, put it on a USB stick and brought it to the location where we had our UserGroup meeting (and they got a vive and oculus there).
When i tried to start the game, the Vive didnt react, the mirrored screen stayed black and oculus home came up. I needed to kill all the oculus home services, only then the vive/steamvr took over.

Is there any way i can change this behaviour? I mean, there will be people that buy my game (well, hope they do!) that have both headsets, and if the default behaviour is to start oculus home then thats pretty bad.
