Good question. Interface #0 does look a lot like a Qualcomm DM/DIAG
function, based on two bulk endpoints, no additional descriptors and the
fact that it is the first interface.  If so, then we do want a serial
driver for it.  There is a basic libqcdm implementation in ModemManager
if you want to test it out.

And I expect interface #4 is QMI/rmnet?  Feel free to confirm that
assumption with a patch against qmi_wwan :-)
