How To Change USB Power Options
Windows XP has a setting that allows users to change the USB power options. This is useful for people who have USB printers that "sleep" after the computer goes into energy saving mode. Some printer drivers do not detect that the computer is in energy saving mode, so the printer is inoperable after walking away from the computer for a long period of time. Changing these settings stops the USB ports from "sleeping" so these drivers continue to work even after the computer is left unattended.
