roywish546 Posted June 19, 2018 Share Posted June 19, 2018 I've been using my vive for slightly over a year now and only until now did it start having problems. I was literally using it yesterday without any issues and didn't touch or break anything overnight. The issue: Turning on SteamVR shows that headset and lighthouses are all connected, but nothing is tracking. Both the HMD and lighthouse icons are solid green, however the HMD flashes for a bit and then goes grey, the lighthouse icons follow shortly after. I've attached a screen recording of what happens Troubleshooting Steps Taken: Reupdating firmware Replugging cables Reinstalling USB devices from developer tab Moving USB from 3.0 to 2.0 and then back Restarting SteamVR Reinstalling SteamVR Restarting Computer Swapping out the HDMI from the HMD to the link box with a working HDMI (also tested the original 3-in-1 HDMI with a monitor and it seems to work fine) Verified that the lighthouses had green light, had B/C on them, all the lasers (15 clustered, and 2 less bright ones on the side and bottom of the cluster) were on Interesting Notes: When I was testing the plugging and unplugging of cables, when I unplug the HDMI, the system seems to work, with the exception of being able to see through the headset. However, all the devices seems to be maintain being green. Another interesting note is that when the devices go grey, you can hear the sound for a USB being removed, not sure if this has any importance. vrserver.txt dump: https://pastebin.com/mG6yjTmH After lots of refreshing, right as the icons go grey, the following messages appear: Tue Jun 19 2018 02:07:41.871 - lighthouse: Lighthouse HMD HID device errorTue Jun 19 2018 02:07:42.070 - lighthouse: Lighthouse IMU HID device errorTue Jun 19 2018 02:07:42.070 - lighthouse: Lighthouse IMU HID device errorTue Jun 19 2018 02:07:42.070 - lighthouse: Lighthouse IMU HID device errorTue Jun 19 2018 02:07:42.070 - lighthouse: Lighthouse Optical HID device error Another message of note that appears frequently in the vrserver.txt Tue Jun 19 2018 02:07:27.292 - lighthouse: LHR-831A737A H: Trying to start tracking from base BAD41914: Available samples not sufficient for booting (hits: 1+2) System: GeForce GTX970, Windows 10 64bit Please help :( I don't know how to further debug this, but this suggests to me that something about the HDMI cable is messing with the ability to detect lighthouses, which makes no sense.
