Hmd Not Found error - Githubissues

chrislatorres commented 5 years ago

SteamVR can sometimes confuse Oculus Go as a HMD when there is no actual HMD. The solution is to unplug the Oculus Go.

an example:

Ideally we'd detect this case and in turn report no HMD's to the site. I don't yet know how OpenVR can be made to do that.

Got a similar error when having Oculus Quest plugged in.
