        That's indeed true...I wonder why that happens - is it the 
joystick that reports itself as having all that, or is it a bug in the 
HID code? I think it's too small of a thing to re-create the driver 
though, it can probably be fixed...

        I know...that's what I'm working on...these last days I merged 
parts of the code from Bjorn and added missing parts to it, so it 
already detects all FF capabilities of the joystick...
