Careful with terminology there. Depending on who you are talking
to (as in most Musicians who use computers), latency means the time
it takes to echo back an input event for monitoring purposes. No
fancy driver stuff can improve that over USB. Ideally for USB, it
would be 1 msec average (1/2 msec for input and 1/2 msec for
output). In practice, it seems to be more like 2-3 msec.
Is this true for Hi-Speed USB MIDI interfaces?
The host can ask the device if it has data to pass at least once per
micro-frame (1/8 ms), so the latency
would be less than that for Full-Speed, I guess.
