Я пытаюсь использовать ModemManager во встроенной системе Linux, которая работает без Network Manager и без udev. Цель состоит в том, чтобы установить sh рабочее соединение rnet с использованием USB-модема DWM-222 (4G / LTE) D-Link.
Я дошел до установки соответствующих драйверов, usb_modeswitch ver 2.5 .2 и ModemManager версии 1.12.6. Я считаю, что переключатель режимов работает нормально. См. Его вывод ниже (обратите внимание на устройства wwan0 и cd c -wdm0).

После переключения режимов я сделал следующее:
- Я поместил файл org.freedesktop.ModemManager1.service в / usr / share / dbus-1 / system-services / , а также в / etc / dbus-1 / system .d / .
- Я также поместил все интерфейсы (xml файлы) в каталог / usr / share / dbus-1 / interfaces / .
- И я поместил файлы .rules в / lib / udev / rules.d / (обратите внимание, что в системе не установлен udev. Он использует его двоюродный брат mdev ).
После этого и попытки использовать модем D-Link через ModemManager меня остановили две проблемы.
ПРОБЛЕМА NR. 1
Первая проблема заключается в том, что ModemManager не может получить имя службы org.freedesktop.ModemManager1. См. Вывод ModemManager --debug ниже.

Обратите внимание, что запущен демон dbus:
-sh-4.4# ps -a | grep dbus
1613 dbus dbus-daemon --system
В какой-то момент ModemManager смог получить служба. Если честно, я столько всего перепробовал, что понятия не имею, что помогло. В любом случае, когда это работало, появилась вторая проблема (описанная ниже), и, пытаясь ее решить, я испортил все, что помогло ModemManager получить имя службы org.freedesktop.ModemManager1. Я попробовал установить fre sh в системе fre sh и снова столкнулся с вышеуказанной проблемой.
(У меня есть подозрение, что все работает правильно, это правильная комбинация dbus-daemon версия и версия ModemManager. В какой-то момент я использовал dbus версий 1.8.10 и 1.12.16, а для ModemManager я экспериментировал с 1.8.0 и 1.12.6.)
ISSUE NR. 2
За то короткое время, когда вышеописанная проблема отсутствовала, появилась вторая. ModemManager работал нормально. По крайней мере, мне так кажется. См. Вывод ModemManager --debug ниже. Обратите внимание, что на этом этапе я использовал ModemManager 1.8.0.

Модем не поддерживается. Неужели это так? Плагин D-Link для ModemManager существует, и в нем упоминается DWM-222.
Затем я попытался обновить ModemManager (до 1.12.6 с 1.8.0), скопируйте только новые плагины в исходную версию ModemManager, которая у меня была , когда это не помогло, я обновил весь пакет ModemManager, попробовал то и это, и в какой-то момент я снова столкнулся с первой проблемой - ModemManager не смог получить имя службы org.freedesktop.ModemManager1 .
Может ли кто-нибудь дать совет, как действовать? Где посмотреть, что попробовать? Мы будем благодарны за любой вклад.
Спасибо.
