Joystick partly not recognised in FS9

Hi,something really strange happens to my FS9 setup:I have some kind of home cockpit that's essentially build around two USB controllers. One gamepad (buttons) and one joystick (buttons and 3 axis). I use the axis for trim and flaps. In FS2002 it works great, but in trying to set it up for FS9 i find that none of the axis are recognised. The buttons on the device (a sidewinder) work though. Everything is OK in control panel and recalibrated over and over, and in Fs2k2 it still works fine too.I can assign the axis to the desired function in FS9 but just nothing happens. Also in FSUIPC the axis doesn't show (no value changes when i move it).I also tried changing functions. E.g. trim on my props lever of the CH Yoke works fine and any other function on the sidewinder axis doesn't. Any clues ?Thanx !Cas
