my experience is limited to a device that doesn't fit your bill (Edirol
UA-25), but at least it simply works. However, USB might not be the
best way to go if you have other options. You can achieve lower
latencies with pretty much everything else, firewire or however those
card bus things are called. If you're just recording or playing back,
that's no problem, but as soon as you need something like monitoring,
the latency can bite you. My device has some direct monitoring option,
probably for exactly that reason, but it is somewhat unsatisfactory.
I guess if you tell us a bit more about your requirements, someone will
be able to give you good advice.
