Assume you meant MC7455, since I don't have any EM7455. But that should
be about the same. Attached a debug log from a short MBIM session,
using all the latest "qmi-over-mbim" branches:
mm: 41708c4681b3 broadband-modem-mbim: try to use FCC Auth through QMI-over-MBIM if power up fails
libmbim: d36c3c7f0bd8 build: bump version to 1.13.1
libqmi: 2372f0405a66 build: bump version to 1.15.1
OK, that's not the latest libqmi commit. I was too lazy to rebuild just
for a build fix ;)
Don't know if this is too useful. I don't have FCC Auth enabled, and we
know that the commands are supported on the MC7455. Anyway, the log is
here. Only interesting piece is the NMEA noise which I still don't know
how to hide from MM.
