so far, so good.

hmm, i didn't see any interface 2 or 3 in your lsusb output.
could you try again "lsusb -v" so that we can check these interfaces?
perhaps they correspond to SPDIF digital i/o.
(these format types are not supported anyway, but it's possible to add
 such funcitionality.)

there was a bug in for getting min/max values of the process-unit and
extension-unit.  
it's fixed on cvs, so please try to update.

strangely, there are some duplicated entires, i.e. the same format,
the same channels and the same rate.
in fact they appear in the usb descriptors.  i don't know what is
difference.


anyway, i'm looking forward to further your results.


ciao,
