Bumping this, since I'm dealing with the same issue.
Whenever I'm using Virtual Desktop, DeoVR registers my Quest 2 controllers as WMR.
Using Air Link makes DeoVR recognize my controllers as Oculus Touch like normal.
SteamVR recognize them as Oculus Touch with both Virtual Desktop and Air Link, so the problem only occurs with DeoVR.
Never used WMR before.
Tried reinstalling and clear out as much as I could find in the regedit, but nothing seem to work.
Been using DeoVR for about a year now and have had no problems until now
