This tip is from Smart Computing.
The most likely culprit is your computer's power management feature, which puts the USB port to sleep after awhile. WinXP puts the USB port, and anything connected to it, to sleep to reduce power consumption. Many USB devices, including many scanners, don’t awaken from sleep mode correctly. To fix the problem, disable power management for your USB port to keep it from nodding off. Click Start, right-click My Computer, and select Properties. Click the Hardware tab and then click the Device Manager button. Locate the Universal Serial Bus Controllers entry and click the plus sign (+) to expand the listing. You should see at least one USB Root Hub. (There may be more than one.) Right-click USB Root Hub and select Properties in the context menu. Click the Power Management tab, remove the check mark next to Allow The Computer To Turn Off This Device To Save Power, and click OK. Repeat for additional USB Root Hub entries, if any.
