<br>What exact version of ModemManager is this? i.e. 1.7.0 is built from
<br>git, so from which commit id? I'd like to know if this very recent
<br>commit was included in your build or not:
<br>https://cgit.freedesktop.org/ModemManager/ModemManager/commit/?id=4e5d8d7e8c0ce16e31d3c98710361eed1cf9f87c
