yeah, right...

If it were so, how would this differ from Firewire? And since using
better cables and hardware which does nothing else DOES NOT improve
the USB throughput, I do not think this is a correct explanation.

Why do you repeat this BS? Having a dedicated USB controller does not
let performance to be anywhere close to the theoretical maximum.

Year, right! Now a presence of Firewire starts to influence USB
performance...

Again: if you know some real technical info, please let us know,
