OptiTrack's OpenVR plugin not compatible with SteamVR 1.26

[ChemnitzScientist]

Hi everyone,

I noticed that the OpenVR driver can apparently not write settings in the format that SteamVR 1.26 expects. SteamVR just did not see the headset, neither for OpenVR 2.2 nor 2.1.1 (which I wanted to use because the Vive Pro is no longer supported in 2.2). I was able to workaround by using SteamVR beta to go back to 1.15 which is fortunately still available, then use the OpenVR driver config tool and then upgrade to SteamVR 1.26.5 again (which I need to do because otherwise my Unity project will not work). This is very inconvenient though, as I will have to go through that process again whenever I change something in my setup.

I would like to see this fixed, and meanwhile, maybe this helps someone.
Thanks and cheers.
