Title: FIXED: SteamVR Error 475 (VRServer failed to start / IPC timeout)

1. Loose or damaged cable – The multi-cable connecting the headset to the link box or directly to the PC is partially disconnected.
2. USB port incompatibility – Using USB 3.0 ports on certain motherboards (especially AMD X570/B550 chipsets) is a known culprit.
3. DisplayPort/HDMI handshake failure – The GPU and headset fail to negotiate a signal.
4. Corrupted USB drivers or SteamVR USB devices – Windows accumulates “ghost” devices.
5. Firmware mismatch – The headset firmware is outdated or corrupted after a failed update.
6. Direct Display Mode disabled – SteamVR isn’t taking exclusive control of the headset’s display.
7. Power management – Windows turns off the USB root hub to save power.
