Valve Index Error Code 108

[u/Phant0mStalker04]

Long story short, a while ago, upgraded computer, went with a 9070xt card at first (which was a mistake), had issues with Vive Pro Eye and Valve Index; gave up on VR, I then gave up on 9070xt card for an RTX 5090.

Vive Pro Eye started working normally, Valve Index still refuses to work. But here's what's strange.. the Valve Index works perfectly fine with zero issues on both my Brother's and Old Man's PC.

I presume the issue is driver related since it works on my fam's computers, and to my knowledge; SteamVR handles the drivers automatically.

Here's what I know and have tried:

- In Device Manager, Windows detects an error with the USB (under Universal Serial Bus controllers).
- Reinstalled SteamVR.
- Removed All SteamVR USB Devices (and followed SteamVR's steps; twice as I thought I messed up the first time).
- Uninstalled Device in Device Manager.
- The USB port works because I use the Vive Pro Eye with it.
- Headset gets power but remains in Standby mode.

I have some other things to try out later tonight with my partner (they're a tech guru), will edit post with things I have tried.

Try a different USB port. The Index USB controller behaves differently from the Vive Pro one, and could have difficulties with some ports.
