This device isn't fully supported yet (see: http://www.pinnaclegameprofiler.com/...pic.php?t=1453), but I've made an imageguide that covers all the buttons and paddles. Enjoy!
FYI: This is an older steering wheel that originally came out for the PS2 but works excellently on PC with Logitech's newest drivers. Force feedback works in the few games I've tried it, e.g. GTR2 and RACE - WTCC.
