Just checked with TARGET Warthog Combined Device and all X,Y,Z,RotationX,RotationY,RotationZ,Slider,Throttle worked.
Could check property window of HOTAS.X?
Well, seems the problem comes from the controller, slider doesn’t work in the propreties window either, tried calibration but does not detect when i move it. Plugged it in other usb ports, same problem.
