The first thing that you would want to do is make sure that you have your software for your scanner before we start making any changes to your configuration. After locating your software, uninstall your scanner completely.  This can be done by clicking on Start --> Settings --> Control Panel. Double-click on the Add/Remove Programs icon. From the list of programs installed on your machine, select the scanner from the list and click on the Add/Remove button.

Now that you have the scanner uninstalled it’s time to turn your computer off. Go ahead and unplug the USB cable out the back of the computer and out of the back of the scanner.  Unplug the power cable from the back of the scanner and out of the power source (the outlet in the wall or surge protector). With everything unplugged, reboot your machine. Check your device manager by going into control panel again, but this time double-click on the System icon and click on the device manager tab. While in device manager look for any yellow question marks or red x’s. Pay special attention to the last device which is the Universal Serial Bus Controller. It is very important that there are no errors on the USB controller, because this is key to your USB scanner working properly.  If there are any errors, please contact the Desktop Support Helpdesk at x5470, menu option #2, to inform them of the error.
