I would even try going into the hardware manager and uninstall the Plextor drivers followed by uninstalling USB drivers. Reboot and the drivers should be reinstalled. USB 1.0 wouldn't be a good thing if that's what you have. If this is the case get yourself a USB 2.0 card. Otherwise try uninstalling drivers and report back to us.
