I recently purchased an original fat PS2 (online pack) and it finally arrived today. The box had been opened, but from the looks of the unit, pack-in game, and the rest it looks like it has had next to no play time...which is a good thing Anyway, after hooking it all up and booting, I found that the controller was not responding (although the analog button works to turn on and off the light)

Next I plugged in one of my newer controllers (just purchased actually) and thankfully that works fine (navigates menus, played a few games...etc)

My question is, why? The original controller is slightly different in the fact that it is more "shiny" and the plug itself has nine pins. The newer model is sort of matte and not shiny and has eight pins. Anyone ever encounter this? Or something as simple as the controller is just shot?
