Twice now after SU8 I have found my track-ir to go non responsive. Both lights are on showing good status but there is no response in the sim. Using the old SU7 toggle in camera settings has no effect.
This is not as frequent as SU7 but there does seem to be an issue now.
Iv’e had this happen twice to me after zooming to the G1000 MFD to do flight plan & freezing TrackiR. The sim loses contact & a reboot of the PC required to get it to work again. Re starting MSFS didn’t fix the issue.
Havent’t played a lot after su8 updtae, because waiting the fix Caravan (etc) FLC is not working, but don’t have problems with trackir yet. Maybe lucky one
thanks for the awesome information.
more “normal one”… there is no issue with TrackIr 
Happend to me as well. The difference is that the right light (connection to the game) turned off. I figgled a bit and it came back (closed application, restarted the game…). Sorry I’m not sure what fixed (by now) the problem.
