I don't think this is presently possible - I think all 8-channel conforming
USB audio devices require USB 2.0 and the only way to get solid audio in or
out of the Pi (as far as I've been able to get working) depends on slowing
the USB to 1.1 speed.  This is certainly just a software thing and I hope it
will eventually get fixed.

OTOH I've been getting good robust stereo in and out using Griffin iMic (and
there seem to be plenty of other even cheaper choices).
