He is saying that because the USB protocol works the way it works, all USB
audio devices have the same latencies. I don't know how that statement is open
to a different interpretation than that all USB audio devices have the same
I know, that the manufacturers of USB cards like to brag with their hardware
being faster than that of the competition, and they would never openly admit,
that a 3 Euro BurrBrown chipset is just as fast as a 600 Euro device - but what
if that's actually the way it is?
