I have a logitech Wingman Formula GP steering wheel that conects to the Game port on my computer. I tried to set it up through 4 button joystic with just a partial succes. When in the game the vehicle will start swiveling slightly making car control very frustrating. For this reason I decided to buy a Game port to USB adaptor at Radioshack. It worked just temporary as I started having the same problem again. I've read a lot about this devices not being suited to Logitech game port devices. I also have heard people talking about wiring it which I see as the most effective solution. Someone send me the wiring diagram but this one was from USB to DB 9 female connector and mine is DB 15. Please if you know how to fix this problem send me the diagram or let me know where to find more information about it I'll appreciatte it. I've tried many places and people with no luck. Thanks.
