HTC Tracker Pogo Pins Crashes UE4

Hi!

As in my question - I have a HTC Tracker 2018 and I want to connect to it a button.
In my Blueprint I recognize this button as a Grip (just like in a normal controller).
Button is connected to pins 2 (GND) and 3 (Grip).

So, when I start my game and move my tracker - location and location works great. But when I’m pressing the button the game crashes.

Is the HTC Role Changer the only way to make it working?

Thanks!

Same problem here. Role changer is not a real option for me since I need both controllers and a vive tracker in my application. Heard somewhere that 4.21 and an updated steam vr software should be able to handle it. But I never managed to get it to work
