Is there anywhere else I could look?  So far I have been able to use the Ozone as the soundcard for some applications, including (finally) Rosegarden.  I can play a MIDI file with some synth plugins.  I cannot control anything from the Ozone; it is not recognized by JACK as a MIDI client.  I was also getting tons of xruns, but I fiddled with the frame rate and other parameters, and it seems to be much better now.

cat /proc/asound/cards
cat /proc/asound/devices
lsmod | grep snd_seq
lsmod | grep snd-seq
aconnect -o
aconnect -i

If I can successfully migrate to Linux for audio, I could get rid of the Ozone (and Pro Tools! Free at last!), but would like to stick with USB so I can use it with my Apple laptop (MacBook with Intel Core Duo at 2GHz).  That's what I run Pro Tools on, and, hopefully, Ubuntu Studio at some point.

the device should work OK AFAIK.

Thats what everyone thinks :)

Your biggest problem is a shared filesystem. There really isn't a good
choice for what to use as a shared common filesystem between any two of
Windows/Linux/OS X. Making it all three is even harder. If you don't
have a common filesystem, it means you have to partition the disk to
hold different filesystems for different boots, and already the system
is starting to look less ideal.
