k_unTrackingStringSize does not exist in vr namespace.

"k_unTrackingStringSize" does not exist in the api (openvr.h). Should I replace it with "k_unMaxPropertyStringSize"?

You don't really need a string that big just to catch the tracking system name. I would change it to 128.

I fixed the buttons in the driver from BetaVR and also added a crouch button. The updated driver can be found here. Since BetaVR no longer supports the driver, let's now join forces in this repository.

Checked in games: Half-Life: Alyx, VRChat, PavlovVR. Everything works well.
