For the EM7455, AT commands might work on the GPS port (eg, the
$$GPSSTART or whatever it was).  QMI LOC support patches were just
recently posted but they would take a bit of time to filter into libqmi
from distributions and thus be available to ModemManager.

For the ME906s, I'm not sure I saw the 'usb-devices' output, so I don't
know if it's in MBIM mode, QMI mode, or AT+ether mode.  That would
affect how GPS might work on it.
