I'm assuming you downloaded the drivers from the manufacturer's site, but just in case:
PNY drivers
[sidetopic] On one of my computers my USB flashdrive works fine in certain ports, but in the other ports it comes up with an error - has anyone ever had the same thing? Do you think it might have anything to do with USB 1.1 vs 2.0? There's quite a few variables, so it's hard to tell.
Edit: I've also noticed some
installation guides, perhaps they may be of some use too.
