Problem with flash drive (u3-related)

I just got a sandisk cruzer 512mb from Staples, and it came with this U3 crap. Well, I got the uninstaller from their website, removed it from my flash drive, and now whenever I insert it, it beeps three times, and then doesn't show up at all.

Anyway, I tried it in my other computer, and it works. It shows up as just the flash drive, nice and clean. I tried another USB device on this computer, and that worked, too.

So, I'm thinking there is something u3-related still on my computer. I did a search (of all files and folders, hidden, etc.) and found a few things. They were in temp folders, so I ran CleanUp and they were gone. Still doesn't work.

There are a few results left, and some I know are from other things. The ones I'm not sure about are:

oc3145u3.ppd
oc3155u3.ppd
oc3165u3.ppd
sym_u3
u3v110

They're all in my driver cache, so they are my main suspects. I'm looking for driver info right now, but if anyone can provide any insight I would really appreciate it.
