Some possible things:
Are you trying to use the ReadeBoost feature? If so if may be that your USB flash drive is not compatable with ReadyBoost.
Is your USB Flash drive USB 1 or 2.0? Vista seems to want to setup the USB ports at USB 2.0 when it installs and might not detect some USB 1 devices. If Vista fails to even detect or identify the USB drive then it might be that its USB 1.
As far as drivers, and your not using the USB Flash Drive for ReadyBoost, you shouldn't really need drivers for it. Vista should be able to detect the USB device with no drivers needed. Unless your trying to connect the USB drive thru an external USB Hub expansion thing or a plug in USB port card, then Vista might have a problem detecting certain USB Drives as it seems right now that Vista has some minor problems with detecting some devices thru these.

Vista can't find drivers for my USB flash drive, and I have no idea what make it is.
What do I do?
