A few days ago, my HTC VIVE Touch Controllers completely broke in X-Plane. They now only appear as "lighthouse" in the controller/joystick menus. The axis' are readable, and I can see inputs for them (Touchpad X, Touchpad Y, and VR Trigger), but no buttons are visible.
I can bind the appropriate commands to the axis', but I cannot bind anything to the buttons, therefore making X-Plane in VR unusable.
I have not installed, changed, or removed ANYTHING close to where the controllers broke.
My best guess is that SteamVR has updated and broke it, but it raises the question of why just me and not others using the VIVE or SteamVR.
