OK. When  trying the adapter it is not auto recognized by XP. Damping won`t cut it, I`ve tryed every imaginable setting.
Gameport I/O range =DC70 - DC77  SB Live I/O range DC40 - DC5F   IRO 18. 
The technical term may be SOL. 
 
 As I stated before setting the second controller up in Windows as either CH Flightstick Pro or CH Pedals is the only way I have found to stabilize it`s appearance in setup for Windows and AH. At one time you said to get rid of The CH software. I asked what you suggested setting the second controller up as. I`m still open to any suggestions. I have tryed many combos setting it up as a generic controller with no luck.
