It's the one from Radio Shack. It never gave me a problem when I was running on my old computer. It is the only thing I'm having a problem getting to work on my new one. I was wondering if it's because I'm using a USB adapter, period. I would like to find a USB controller to try, but I can't find one for sale anywhere. If worse comes to worse, maybe it's time to move on to one of the new sims...G3 or Reflex. It's funny, G2 worked well on my old computer, which just barely met the requirements, now I have one that is more than I need, and G2 doesn't like it.
