SteamVR has this iffy feature, where by button mapping can be done only if the device is attached. This is why I went yesterday to Helsinki XR Center. Yep, they got the WMR headset, but one of the controllers was broken. So - dead end.
This morning I ordered second hand WMR headset, waiting for to get it on friday. Before the mapping is done, I'm kinda stuck as I need to get this new rig to every scene.
