When comparing USB 1.1 and FireWire, FireWire is the clear winner.
There really isn't any comparison presuming price isn't a factor (USB
is definitely cheaper). The biggest factors that make FireWire better
are the higher throughput and the much more stable and higher
resolution timing.
For USB 2.0, as you say, the audio class spec is still not quite
finished. From what I know, it sounds like the committee is learning
from the mistakes of 1.1 as well as including some of the nice things
about FireWire. That said, we won't really know if USB 2.0 will cut
the mustard until the spec is finished, hardware starts shipping, and
we get a chance to bring up a driver for it.

Can anyone comment on the preference of USB or Firewire for
professional audio?
It would seem that USB is more ubiquitous and with high speed
operation, it should work well. And yet, looking in the
marketplace, the Edirol UA-101 seems to be the only product that
uses USB 2.0 high-speed multi-channel, high frequency I/O. Most
products use FireWire.
Is it because the USB 2.0 Audio spec has not been completed?
(Speaking of which, does anyone know when it will be complete? Has
it faltered in the committee?)
Are there technical hurdles that make it more difficult to bring a
USB audio product to market?
Today I watched the replay of the Audio Hardware and MIDI session
(205) from the last WWDC. It suggested that USB was for hobbyists
and FireWire was for Pro applications. However, it was comparing
the USB 1.1 speeds.
One concern we have is for maintaining our clock. Would we have
more jitter on USB than FireWire?
Thank you for any comments and real world experience you can share,
