USB audio

[toyfactory]

I have an Audiotrak Maya44USB sound device that I'm trying to get
working.  It doesn't seem to get detected at boot-up but if I plug it in
after boot-up it shows up in the Device Manager as a USB Audio
Interface.  It doesn't seem to have a corresponding entry in /dev so I'm
not sure how to access it.   If I type lsmod, I can snd_usb_audio listed
there, so I'm guessing the necessary module is installed.  I'm using
XMMS and I'd like to find a way for either the ALSA or the OSS output
plugin to talk to my sound device.

Any ideas?
