I'm currently running Logitech profiler with a DFP and a FF GP (pedals only). The problems I've found with it is that if I assign a key to one button on one device it assigns it to all the devices.

I'd like to be able to make an H gate shifter out of a Logitech Wingman Joystick, the problem is assigning the wheels to get correct FF. I can assign the DFP as ID 1 but LFS still won't get do FF (it seems it only supports 2 controlers).

So I'm looking for an alternative program or even better an H shift app that stops the joystick being read as a normal controler.

Have a look for FFShifter on RSC's custom/homebrew cockpit etc forum, does exactly what your looking for. At one point I had my DFP setup for FF in LFS, FFshifter using my Logitech Wingman for shifting and it controlling the FF, and another controller to use as a clutch pedal. LFS worked fine with this setup, the end result is it sees the shifter "zones" for the gears as button presses, and not as an independant device.
