The TWAIN software that most likely came with the scanner. Or the Software
that is on the Mustek German web site.
You have never given the model number of the scanner so, I can not check the
site to see if there is a TWAIN driver on site.
http://www.mustek.de/eng_/start_english.htm

Click on Drivers.

If you did a NO, NO. (Plugging in the scanner to Windows XP before
installing the software).
Then you have to go into the Device Manager and remove the WIA driver for
the scanner, You may need the scanner connected and turned on for it to show
in the Device Manager.

Device Manager is found at Control Panel>System, Hardware tab Click Device
Manager button.

After removing in Device Manager, unplug the scanner from USB, reboot the
computer. Install the correct software, reboot the computer. Now plug in the
scanner and turn on.

In Windows XP never connect a device before installing the correct software.

Windows XP has some built in drivers for some devices, but WIA is a poor
substitute for the manufacturers TWAIN software.

By changing the plug (cable) in back to another connector. Most computers
have 4 USB connectors on the rear of a computer, each connector is a
different USB port.

Does the Mustek have a power switch?
If so turn off the power when not using the scanner.

USB is the best thing that was invented for computers in a long time. Most
of the bugs have been ironed out in XP SP2. If you do not have Windows XP
Service Pack 2, I suggest you go to Windows Update and Update to SP2.
