you have built your module with debug=full?
can you then do something like this in a console:
dmesg -c
aplay file until sound starts getting croaky then immediately conrol+c
dmesg>dmesgfile
and then send dmesgfile to me?
also please attach a lsusb of the us122. and the changes you applied for this
test.
(Just for Information
the lsusb of the us428 here gives:
