Ok, forget the last above comment. My mistake---usb-audio is a module, 
it is not in /dev/snd. I found it under 
/lib/modules/2.6.13-15.7-default/kernel/sound/usb. When I type in the 
command 'ls -l /lib/modules/2.6.13-15.7-default/kernel/sound/usb' I get:

total 136
drwxr-xr-x   3 root root  4096 Dec  7 19:32 .
drwxr-xr-x  11 root root  4096 Dec  7 19:32 ..
-rw-r--r--   1 root root 98896 Nov 29 16:54 snd-usb-audio.ko
-rw-r--r--   1 root root 19864 Nov 29 16:54 snd-usb-lib.ko
drwxr-xr-x   2 root root  4096 Dec  7 19:32 usx2y


'usx2y" is blue; snd-usb-audio.ko and snd-usb-lib.ko are black.

hope this helps and thanks again,
Dominic
