I seem to recall that one of the slower USB versions was renamed to USB
2.0 or something like that to make it more marketable when the higher
speed USB 2 came out.  I think one is called "fast USB2" and the other
"high-speed USB2".

The nomenclature for USB2 and the design bandwidths are:


USB2 Low-speed: 1.5 Mbps
USB2 Full-speed: 12 Mbps
USB2 High-speed: 480 Mbps

So make sure the cable, device and PC says "USB2 High-speed"! They have a special logo to indicate that.
