Hi Takashi and everyone,
Luis just got back to me, and he's not the right person to talk to about the snd_usb_audio. http://alsa.opensrc.org/index.php/Usb-audio#Notes suggests I contact Takashi Iwai. Quoted below is the message now available at http://mailman.alsa-project.org/pipermail/alsa-devel/2007-November/004552.ht... (you can get the patch there, or on the wiki).
I'm just new to alsa-devel, so I'm trying to connect with the right maintainer.
Cheers, David

Hello Luis, and Alsa list,
I recently got an Edirol UA-4FX. It works just fine as a generic USB Audio device. I've written up all the details at http://alsa.opensrc.org/index.php/Edirol_UA-4FX (shamelessly stolen from the Edirol_UA-25 page).
The the UA-4FX needs a patch to usbaudio.c create_ua700_ua25_quirk() and usbquirks.h, and then it has full support. (MIDI I/O, sample rates up to 96 kHz) I've made an attempt, mostly to get it working on my machine. Can you review it?
Thanks, David
