Adreno cards / Potentiometers to USB

Hi All,

 I had made a slide potentiometer throttle when I had the creative audigy card which had a gameport , but the card blew and now I need to use it on a USB port and this is especially for the Cessna 172 and later 152 for X plane 10. Does anyone know how can I do that.

 The other thing is about the Adreno cards, has anyone tried using those to make gauges like the comm / lights etc .... ?

 Thanks guys.
