Good Afternoon, i opened a ticket with STEAM as well but i wanted to post this in hopes that someone out there knows how to work this issue. Ok, Here goes. T/S with HTC Vive 6 chat support techs over 6 hours. The Issue: my HTC Vive Controllers button mappings are wrong. trigger press on one does nothing, system button acts as trigger but also performs a screen shot. in some games and doesnt work at all in others. In steamVR home, i can bring up the paint tool and triggers both work fine. It is 100% software or firemware issue. One more symptom i noticed was when i run room setup, the step involving pointing at the monitor instantly fills up without me pressing the trigger button.
T/S steps so far: reset controllers, ran as admin both steamVR and Steam itself, removed all power to pc and link box for a few minutes and restarted, reinstalled SteamVR, reinstalled steam itself, uninstalled bluetooth device, unplugged all other controllers/steering wheels/etc, sent system report to chat support, ran multiple malware products just in case, tried changing button mapping. I even installed my vive on another PC but the problem followed the vive.
