@Doug: Can you tell me/us more about your new interface? My personal interface will support an infinite count of joysticks/gamepads/wheels with forcefeedback and so on. You can start/stop the plugin within the game and you can choose, if you wanna use the Xbox 360 controllers with DX or with the Xbox interface. You can define a msg handler that recognizes new joysticks or de-/reattached joysticks. Joystick handling is very easy like

if(Button_1(hJoystick1)== on) { Name_of_Joystick(hJoystick, strJoystickName); }

All values are between -1000 and +1000 for axis (not +/-255). You can set null and dead zones. You can load forcefeedback effects from file (Force editor to test effects and to write into a file included) and you can define forceffeedback effect by code.
and so on.... If your new interface is similar fine I stop my project (70% done), I don't wanna waste my time (didn't see anything in the forecast or anywhere else).

@William: Thanks, I'll look into this this evening!
