Not necessary.
If you buy this one:

You can hook your Suncom SFS to your system to this adapter.
You still need the keyboard pass through for programming.
I use 2 keyboards;one is hanging at my system the other for the SFS.
Windows 7 recognizes it as a 4 button, 4 axis joystick.
You can choose from 4 different types on the adapter itself.
Works perfect! Calibrating is a bit of a pain;you should take your time for it.
But when thats sorted , you have dual throttle,which works perfect in FC2.
For me , i had no issues installing my Suncom.Windows 7 Professional x64.
Q6600, 8G DDR2-800 ram.
Hope this helps some pple out.
