Check to make sure you've enabled USB 2.0 in the BIOS.

Subject: [PCBUILD] USB Ports and its speed

I recently bought a Canon CanoScan 8800F scanner and it supports Hi 
Speed USB 2.0. I connected it to my computer a AMD GA-M57SLI-S4 
motherboard. When I turn on the scanner I get the message "This USB 
device can perform faster if connected to a Hi Speed 2.0 port."
How can I tell the speed I'm running at? Since they say that the Hi 
Speed runs 40x faster then USB 1.1 there would be a major difference in 
performance.
The motherboard manual just says it supports 2.0/1.1. The Hub I'm 
running it through supports Hi Speed 2.0 and is self powered.
