There has always been an issue with windows xp and hibernation program. This is another one of the issues. Another work around is to disable the hibernation availability.
start > control panel > power options > hibernate tab and un-check the hibenate box.

Microsofts' fix is to leave the USB 2.0 disabled indefinately...the work around this is to go into device manager and uninstall the USB controller driver...reboot...let windows re-install the drivers and then reboot again...you might need to visit windowsw update for a newer USB 2.0 driver.
