This won't help to solve your problem, but if I understand the above
trace correctly the ZTE dongle is also presenting itself as
containing mass storage.
Seems like the long-term solution would be to add a quirk (if at
all possible) to ignore the storage part.
Looking at usb_quirk(4) this might help: UQ_MSC_ALT_IFACE_1
but I'm not certain.
Anyway, take a look at the manpage, because it's possible to set a
quirk in loader.conf.
