As you can see, SteamVR error 108 (headset not detected) usually happens while users are using HTC Vive headsets.

Don’t worry if you have the same error code. In the following contents, you can find some effective solutions, and please have a try.

Method 1: Restart Your VR Headset

Sometimes a simple restart can fix common issues. Therefore, when you get the SteamVR error 108, the first thing you should try is to restart your computer. Remember to close SteamVR before that.

If error 108 (Steam VR headset not detected) still exists, you might need to reboot your headset. You just need to right-click the headset icon in SteamVR and select Reboot Vive Headset. Then wait until the process is finished. After that, check whether the error code disappears. If it pops up again, move on to the next method.

Method 2: Check Your USB Port

You should have noticed an essential device for the Vive VR experience, Vive Link Box. With a female HDMI and a USB Type-A port, it is the link between your PC and the Vive VR headset. Therefore, to solve HTC Vive error 108, you’d better make sure the USB port on your PC works well.

You can try plugging your Link Box into a different USB port on your computer, especially a USB 2.0 port. It is because some USB 3.0 and 3.1 are not compatible with the headset. If you have connected your keyboard or mouse via a USB port, you can try plugging your Link Box into this USB port and check if it works properly.
