Vista - Vista crash has messed my system

My problem is similar to the one descirbed in the earlier thread headed "USB
Mass Storage Device."

Vista crashed while a USB thumb drive (Kingston Data Traveler 4GB) was
connected, and while it was in the middle of preparing an encrypted partition
using TrueCrypt. Now I've got real trouble. The USB device is inaccessible.
Device Manager shows it but with an exclamation mark on its icon and the
message "This device cannot start. (Code 10)." I think Windows believes the
USB device is a CD drive, since it shows a non-existent h: CD drive. I have
tried everything I can think of, inluding trying to update the driver (Vista
says I already have the most recent driver) and uninstalling the driver
(hoping that Windows would re-install it and recognize my USB device).
NOthing has worked.

(Don't even ask about how Vista crashed at least 4 times in my first week of
owning it, while I'm not sure XP ever did.)
