I believe Ryan Gallagher said this around Tue, 12 Nov 2002:

Can you get it working in just half-duplex? (like 'pd -audiooutdev 4')

It looks like it *might* be the long-standing portaudio mac_core failure
to handle full-duplex across USB interfaces that present themselves to
coreaudio as multiple devices. However, relatively recently Phil Burk
made some progress in improving this shortcoming:

Although I've been watching this issue, I don't have any external devices
to test on. (But I'm in the market--I was considering the Edirol UA-5,
but the reviews here lately have put me off that.) You might like to try
experimenting with a current CVS snapshot and 0.36-test5. I'm looking at
it now, too.
