You are probably right about USB3 but with USB1 and USB2 speeds, how
can the clock speed not be relevant? As an example, wouldn't
transferring 1024 frames of float on USB1 (12Mbit) take 2,7ms and only
68us on USB2 (480Mbit)?
In raw throughput that is, there are probably other factors limiting the speed?
