ouch!

i'm a (not so happy anymore) owner of a us224 which does all the same 
path as your us122,,.

i am sloppy and the systems i use this lovely piece of h/w is not what 
you'd call the latest and greatest

so (my) the state of things at the time of this writing, is the following:

- on 3.4.x-rt it still works but only like a plain usb1 device (-r48000 
-p128 -n3); good old and awesome, special fast and low-latency 
rawusb/hwdep mode of operation is dead. or it seems so

- on 3.8.x-rt it doesn't work at all; always nagging the device's being 
used by something else (and no, it's not pulseaudio:); and if you dare 
to use jack1 then, well, it just crashes the whole show (kernel oops)

only tested with preempt_rt though (thus the -rt suffix above)...

i know this does not help in anything but at least you're not alone :)

cheers
