The card shows up under '/proc/asound/cards', but only as Midi. See
attached for full listing.

Was running as root (on Xubuntu, 2 different machines, different installs).
I note that sometimes this is OK, ie when I do '# echo 0 >
/sys/bus/usb/devices/1-2/bConfigurationValue', but then I have no
interfaces at all (no midi, no listing).
Can anyone confirm they have a US-122L working on a new kernel. Is the USB
descriptor the same as what I'm seeing, perhaps hardware changed at some
point.
Cheers,
Simon
