Error 108 (Headset not found)
This error may be a USB driver issue. Please try the following troubleshooting steps:
Reboot your headset:
- Right click on the headset icon in SteamVR.
- Select Reboot Vive Headset, and wait for the reboot process to complete.
Power cycle your Link Box:
- Quit SteamVR
- Unplug the Power and USB cords from the PC side of the Link Box (not the orange side).
- Wait a few seconds, then plug the Power and USB cords back into the Link Box. You may see more drivers install. Wait for this process to finish.
- Launch SteamVR.
- Repeat steps if needed
Restart your computer (Quit Steam VR before shutting down your PC)
Plug your Link Box into a different USB port on your PC:
- Try plugging your Link Box into a USB 2.0 port, as some USB 3.0 and 3.1 chipsets can cause issues.
- You can also try a USB port that's already in-use and working -by moving the other device to another port and plug in your Link Box to the port.
- If this problem persists, try resetting your USB devices.
Error 109 / Error 400
You may see one of these errors if you are not connected to your machine's dedicated graphics card.
Please make sure that both the Vive's link box and your primary display are connected to the same GPU. If you are using a laptop, make sure that you are connected to the machine’s discrete GPU. You may need to set your machine to "prefer maximum performance."
Additionally, if you have multiple graphics cards in a desktop PC, make sure that the Vive and your primary display are connected to the same card. Some users have reported that connecting their primary monitor over DVI causes issues next to the Vive. Try using a display port or HDMI connection.
Error 208 (HMD detected over USB, but monitor not found)
Error 208 is a generic HMD error message. This error can have a number of solutions, so please work from the list below to make sure you've attempted all available solutions:
- Make sure that your Vive’s link box and the monitor or TV you use as a primary display are plugged into the same graphics card. If you are connected to your onboard display adapter, you will see an Intel HD Graphics device listed in your SteamVR system report. Onboard cards, such as those connected to a PC’s motherboard, will not be powerful enough to use the Vive. Reconnect your Vive to your PC’s dedicated graphics card.
- Check to make sure you are in Direct Mode by going to Settings > Developer > Direct Mode. Click the button that says “Enable Direct Mode.” SteamVR will restart with this setting.
- If Direct Mode is not enabled, SteamVR will still work in Extended mode. For this to work correctly, make sure your displays are extended in Windows > Display Settings.
- Make sure all cables are connected firmly. The power cord on the HMD itself can become loose from usage. To check this, remove the cable panel on top of the HMD by pushing it forward.
- Make sure your Link Box is installed in the correct direction. The orange tipped cables from the Headset should be connected to the orange ports on the Link Box.
- Check to make sure you have the latest video drivers.
