Q:
What should I do if this message appears in Windows XP: “A HI-SPEED USB Device is Plugged into a non-HI-SPEED USB Hub”?

This message is not an error. It indicates that Windows XP recognizes that a USB 2.0 device (the scanner) is connected to a USB 1.1 port. The message is not an error. You can close the message by clicking in the right corner of the message title bar.
