What can I do to resolve the "headset not found" error?
Do the following steps to troubleshoot the issue:
- Close all Steam apps on your computer, including the SteamVR app.
- Unplug the link box cables (HDMI and USB) from your computer, as well as its power cable from an electric outlet.
- Wait for a few seconds, and then plug the cables back in. On your computer, you might see a notification that drivers are being installed. Wait for the installation to finish.
- Restart the SteamVR app.
If you still get a similar error, repeat the steps again. You can also check if you're encountering a USB-related issue. For more details, see My headset can't be detected due to a USB port issue. What should I do?.
