I have an Edirol UA-1000: it was one of the first USB2 audio devices
made, and has its own kernel driver (common with the Edirol UA-101,
which superceded it). AFAIK it's not class compliant with either USB1 or
USB2. It has 12 inputs and 10 outputs.
jackd runs very nicely with:
/usr/bin/jackd -P89 -t2000 -dalsa -r44100 -p256 -n2 -D -Chw:UA1000
-Phw:UA1000 -zs -I110 -O110
Hardware is a Dell Vostro 1520 laptop, Core2 Duo 2.4 GHz P8600.
Other software is Ubuntu 10.04, vanilla kernel from kernel.org
(currently 3.0.4), and jack1 from svn.
I get the occasional xrun if I forget to disable CPU frequency scaling
and the DSP load gets high, but otherwise it goes all day xrun free with
these settings.

actually, it almost doesn't matter because almost all of the USB audio
devices that work on linux are USB1; even if you have a USB2 device,
i'd be interested in hearing about that too (assuming it works with
linux).
if you can run a USB 1 class compliant audio device
And how do I figure out if the device is usb *1* class compliant?
