Steam VR touchpads stop working when changing scene

Greetings,

We are immersed in the development of a VR Experience for HTC Vive and Unity.

We found a extremely annoying problem. We have found out that Touchpad stops working when loading a NEW SCENE. If a new scene is loaded, we need to turn the controller off and then on, so we can use Touchpad. If we don't turn it off and on, all triggers/buttons work properly except Touchpad.

Has anyone experienced anything similar? H

Thanks in advanced.
