This is not something we can use as a workaround, since you'd be losing
USB2 which has a purpose (otherwise it wouldn't be provided).
This needs a fix in the modemmanager whitelist udev rules, or in the
kernel driver in use.
These are the revelant udev lines from modemmanager's
/lib/udev/rules.d/77-mm-zte-port-types.rules:
ATTRS{idProduct}=="0033", ENV{.MM_USBIFNUM}=="04",
ENV{ID_MM_ZTE_PORT_TYPE_MODEM}="1"
ATTRS{idProduct}=="0033", ENV{.MM_USBIFNUM}=="01",
ENV{ID_MM_ZTE_PORT_TYPE_AUX}="1"
Could you please run 'sudo lsusb -d 12d1:0033' with the device plugged
in, so we can see if there's something going wrong with how the ports
are detected?
I suspect what is likely required here is either that these values are
plain wrong, or as a more likely scenario your device uses a different
firmware version than what was tested and lists its ports in a different
order.
