Power surge on hub port????

[jk]

What does this mean? XP shows this after resuming hibernation, not when
starting windows "normally". I don't even have any USB devices attached to
computer, but all the three USB ports are working. Computer is Acer
Travelmate 2301.

Suggest, if this PC is under warranty, to contact Acer tech support.
