When SteamVR encounters an error, it will typically display a 3-digit error code along with it. While these errors can usually be resolved with a quick restart of SteamVR (or sometimes even a re-install), some require additional attention.

Error 108 – Headset Not Detected

Error 108 is caused by issues when finding your VR headset. The ambiguity of this message means finding a solution can prove to be difficult, with both software and hardware being potential culprits.

  • First, restart SteamVR. If this does not fix it, close the program completely and proceed.
  • Ensure all cables are securely connected between the headset and the computer
  • Power Cycle the Link Box - disconnect it from your computer and power. This includes USB, HDMI, Power.
  • Wait couple of seconds and then plug Link box back in
  • Wait for the Driver install to be over.
  • Start SteamVR - If connectivity was the issue, the error should be gone
  • You can also try plugging in to different USB ports, as there is a chance the specific USB port on your PC is bad.

Error 113 – Path Registry Not Writable

This error code is related to issues with user write permissions with SteamVR. 

  • To ensure SteamVR can save to the required paths, check that your permissions allow for writing to your PC's user directory.

Error 200 – Driver Failed

Error 200 is provided after issues arise with the OpenVR driver, which often relate to insufficient user permissions. This can also be caused by conflicts in the SteamVR driver directory.

  • If you've manually added any unapproved files or drivers to this library, these should be removed.
  • Check to see if you have set up your permissions properly. You will need to make sure that you are able to write to the user directory of your machine.

Error 206 – Driver Not Calibrated / Error 207 – Driver Calibration Invalid

Both of these errors are caused by calibration issues, encountered when the calibration file can't be loaded off the headset. If this issue is encountered, Valve recommends the following fix"

  1. Unplug your VR headset from your PC.
  2. Open the SteamVR desktop application.
  3. Open the SteamVR drop-down menu. Navigate to Settings > Reset.
  4. Click Remove all SteamVR USB devices.
  5. Reconnect your headset and wait for the drivers to automatically reinstall.

If the issue still persists, this may be an indicator of a faulty headset. If you suspect this to be the case, contact your headset manufacturer for more information.

Error 208 – HMD Display Not Found

This error is the result of your VR headset's display not being detected. 

  • Check all cable connections and ensure they are connected properly.
  • The 3-in-1 cable can become loose with time and extensive use - It may need replaced
  • Check the connectivity of your Link Box. See if the orange ports that are coming from the headset are connected to the orange ports that are placed on the Link Box
  • Ensure you have the latest video drivers.

Error 300 – SteamVR failed to initialized for unknown reasons

Error 300 is a somewhat rare error to receive in SteamVR and if it does appear, can often be fixed with a complete restart of your PC. With such a vague error message, it's often hard to pinpoint the exact cause of the problem if this appears frequently with your installation.

  • For many people encountering Error 300 repeatedly, some have found that privileges are the source of this issue. By ensuring the Steam is run with administrator privileges, this can remove some unwanted restrictions placed on the program.

Error 301 – Connect Failed

Error 301 is a relatively common error for many SteamVR users, caused by an inability to start or connect to vrserver.exe. This is often caused if the executable is already running, which can be identified via Windows' inbuilt Task Manager. 

  • If vrserver.exe is running, quit the process and attempt to run SteamVR again.

Error 302 – Init Failed

This is caused by issues when starting up vrserver.

  • Reboot your PC and launch SteamVR.
  • If this does not solve your error, send a system report.

Error 1101-1112 – USB Error

Errors 1101 through 1112 are the result of USB failures, likely caused by driver issues. If encountered, we recommend following the below steps:

  1. Unplug your VR headset from your PC, including any related accessories.
  2. Open the SteamVR desktop application.
  3. Open the SteamVR drop-down menu. Navigate to Settings > Reset.
  4. Click Remove all SteamVR USB devices.
  5. Reconnect your headset, alternating between various USB ports. Once detected, wait for the drivers to automatically reinstall.
