That matches my memory of it; it's not an OS thing. I mentioned similar in a recent thread where there is a difference between a SC manufacturer who's sole purpose in life is audio interfaces vs. some company in the music business that decides to sell their own "branded" interface - the latter is almost always some hodgepodge of existing designs which in turn use windows (or the mac equivalent) of generic class compliant drivers - which come with a latency penalty.

That said, when someone does it right (RME in this case), USB is clearly capable of real-world workloads. PCI can beat it but in my experience of just "getting on with the job" so to speak, I don't notice the fact that my RME USB/Firewire isn't PCI even when recording 24 simultaneous tracks over USB2.
Music is what feelings sound like.
