Well don't despair, there is a generic Joystick Plugin that takes motion cues directly from the input of your peripheral controllers instead of the game, you can grab it here: http://www.xsimulator.net/community/marketplace/joystick-plugin.127/
As @auryza suggests you can use the "Xbox 360 Controller Emulator", to make any controller act like a xbox360 controller: http://www.xsimulator.net/community/threads/joystick-plugin.6160/page-2#post-107565
