Unfortunately there seems to be a trent with the "profesional" audio
people to never release any programming specs for anything.  Most of the
drivers are done by reverse engineering or trial and error.  That is if
someone has the hardware (few programmers tend to also be high end audio
nuts), and wants it working badly enough.

What does /proc/asound/cards list?

Does lsmod show snd-usbx2y loaded (or whatever the driver name was)?

What kind of USB controller do you have?
