Regarding NDISCONN instead of NDISDUP; Dan also had some questions
about that, see:
http://lists.freedesktop.org/archives/modemmanager-devel/2014-July/001414.html

One of the things you need to check with that modem is whether the
NDISDUP command is sent in the /dev/cdc-wdm port instead of in a TTY;
I believe that the modems handled by the huawei-cdc-ncm driver in the
kernel need to have the NDISDUP command in the same USB interface as
the WWAN port, which is what huawei-cdc-ncm allows to do.
