Powering the MS9520-47/MS9540-47 directly from the computer can sometimes
cause interference with the operation of the scanner or the computer. Not all
computers supply the same current through the keyboard port, explaining why a
scanner would work on one computer and not another. Contact a Metrologic
Customer Service Representative if you require an external power supply.
