Hello,
I've recently updated my Windows 7 Ultimate installation to Windows 10 Pro (using the upgrade functionality).
Since then, I have one major issue with my Saitek X-55 throttle and FSUIPC. The problem is that FSUIPC does not detect axis and button inputs from the throttle unit. This in both FSX and P3D. If I start the sim, open FSUIPC, and go the axis calibration tab, nothing happens when I move one of the axis. Same thing for buttons, on the respective tab.
The X-55 stick works fine though, it's just the throttle. Similarly, the throttle works perfectly if I don't use FSUIPC.
