I'm with a US-224. Also USB1.1. With the nrpacks=1 parameter on the
snd-usb-usx2y driver (alsa-1.0.8+), you can bolt on the "rawusb" mode
jackd alsa backend (jack-0.99.43+) and achieve latencies on the order of
3ms (-p64 -n2). But there's a catch: this only works stable provided you
run a well tunned realtime-preempt patched 2.6.11+ kernel, as the one from
Ingo's :)
Bye.
