Hey, I’m having a really weird issue with my Valve Index and I’m running out of ideas, so I wanted to ask here before I assume something is broken.

My Index was working fine at first setup. When I first connected it, it actually worked normally and showed my desktop when Direct Mode was off (so the display over DisplayPort was definitely working). I was able to continue setup and everything seemed fine.

About an hour later, after I had mounted my base stations and didn’t change any cables or anything, the headset suddenly stopped being detected.

Now SteamVR just says “Please plug in your VR headset” even though everything is still connected.

Some context on the cable: it’s not heavily used. I bought it about 1.5 years ago, but I’ve only used it maybe 5 times total because I didn’t have a proper setup during moving, so it’s mostly just been stored in its box.

What still works:

Windows detects the USB connection (USB connect sound plays when plugged in)
Device Manager shows it as USB Composite Device
The headset can still show my desktop when Direct Mode is disabled (so DisplayPort output works in monitor mode)
Webcam seems to work when opening camera app

What does NOT work:

SteamVR does not detect the headset at all
Direct Mode doesn’t work anymore
It also doesn’t get detected on a second PC

Things I’ve already tried:

Reconnecting all cables (USB, DisplayPort, power, breakaway connector)
Different USB ports on two different PCs
Restarting both PCs multiple times
Reinstalling SteamVR completely
Removing SteamVR USB devices and resetting SteamVR settings
Deleting SteamVR config and driver folders
Renaming/rebuilding SteamVR driver files
Resetting GPU driver state (Win + Ctrl + Shift + B)
Updating AMD drivers
Testing on a second PC (So my PC with AMD and GFs PC with NVIDIA both same issue)

Has anyone seen this kind of “USB works but SteamVR refuses to detect headset + monitor mode still works” situation before?
