PNY Attache USB 2.0 Flash Drive

If the USB drive is not recognized after you plug it in, there is usually a simple reason.
Either the USB port is not active, the Port drivers need to be reinstalled, the system is unable to assign a drive letter to the new device, or most commonly... the drive loads software as soon as it is inserted and this software needs to be updated.

Remember that Vista Ready does not necessarily mean that it is ready as-is.

Try the stick on an XP system to verify that it works.

In case this is a 'Smart Drive,'
I also found this page on the PNY support site that has a link to download a Vista update for the U3 Launchpad software. (the link is in the lower right section)

Good Luck.
