HMD lenses flash white 3 times, red light on left side. in Vive and Vive Pro Posted October 6, 2018 I didn't roll back drivers, but I just went into the SteamVR settings and removed all USBs, using the devoloper tools. Re-plugged in Vive, reboot, and it loaded all the drivers again for the headset. After that, I haven't had another issue, so far. If it comes back, I'll do further testing.
