You sure its not "USB 2.0 Full Speed" (aka 1.1), instead of "USB 2.0 Hi
Speed" (usb 2.0 / 480mbits) ?  A lot of vendors now call their 1.1 stuff
"2.0 Full Speed".

"USB 2.0: Revised in December 2002. Added three speed distinction to 
this standard, allowing all devices to be USB 2.0 compliant even if 
they were previously considered only 1.1 or 1.0 compliant. This makes 
the backwards compatibility explicit, but it becomes more difficult 
to determine a device's throughput without seeing the symbol. As an 
example, a computer's port could be incapable of USB 2.0's hi-speed 
fast transfer rates, but still claim USB 2.0 compliance (since it 
supports some of USB 2.0)."
