Did you read and follow the HP instructions?
You install the scanner software first, before you connect
the scanner.
Then you plug the scanner in, when directed by the
installation program, and the drivers are installed.
If you plug the scanner in first, XP will install its
default drivers and the scanner won't work or it won't work
correctly.
Remove (unplug) the hardware)
Use device manager to remove the scanner and if necessary,
the USB ports...then reboot and install following the
directions.
