Even with my purposeful WMR / SteamVR opening sequence I’m still getting the black screen issue. Strangely, I only get two.. separated by about 5 - 10 seconds. Then it will never do it again for the session. Some type of software issue may be at play. Who knows????
I really enjoy my G2 but if a better quality / less quirky headset, such as an Index with high resolution, comes out I would upgrade.
At least mine is usable. I feel bad for you Alpine, being totally out of service.
Speaking of usb issues. Have you tried plugging in everything with exception of the power plug at the little power brick. I had a supplemental card inside my box that specified this sequence, with power being the last thing to plug in.
