Thanks for your comments, it turns out the cables for the psp was the problem not the drivers on the pc. Took the pc to Circuit City and the Tech used his cables and the file open. I asked him to try my son's cables and sure enough they didn't work. He gave us a set of cables and everything is working great. Prior to that Dell has reinstalled the drivers for the USB ports and still it didn't work. Thanks again.
