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 :-)
