NM 0.7.1 and later probe modems dynamically to figure out their
capabilities. But it doesn't probe devices driven by 'usbserial' since
they are not generally supposed to be 3G modems.
Your 3G modem USB ids should be added to 'option' (for Option, ZTE,
Huawei, Novatel, etc devices) or 'sierra' (for Sierra devices), because
those drivers enable the high-speed communication that 3G devices are
used for.
usbserial is not built for high-speed communication and thus your
transfer rates will be quite limited. If you add your modems IDs to a
known mobile broadband driver (like 'option') it should get picked up by
NM.
