@PimaxQuorra so I’ve had a few responses from them now including the complete uninstall/reinstall, and checking the silicone cover wasn’t obstructing anything. They’ve decided a remote session isn’t needed and the headset should be RMA’d. Whilst I appreciate their wanting to get to the bottom of things, an out of warranty RMA just to get the hand tracking working would be a bit of a silly expense, especially when they can’t give me any ballpark figure of what it may cost (with shipping etc I might be paying 50% of the headset cost, and I wouldn’t know until I had to to get it back).
It looks like I’m just going to have to get a long USB cable and stick the unit to my headset, and hope they find a “broken” unit they can test so they can find out what the issue is. I’m still betting it’s either firmware, or WIn10 conflict issues.
Have a great New Years
