Периодически отваливается модем

1

Добрый день!
Использую модем только для отправки алармов по SMS. Заметил, что периодически модем пропадает, перестает мигать лампочка на контроллере, смс-ки не ходят.

Судя по логам, отваливается весь USB:

Как оказалось, проблема существует давно, но так как периодически перегружаю контроллер, я ёе редко замечал:

Подскажите, в чем проблема, как диагностировать?

Добрый день.
Посмотрел, увидел что соединение так же прерывается. Не совсем диагностика, если канал не пользуется приоритетом.

Вот вывод MM показательней, совпадает с dmesg.

Спасибо, написал. Теперь понятно, почему я не смог в свое время обновить образ с флешки, и не смог заставить работать Z-Wave донгл. Оказывается, в целом с USB проблемы…

Возможно, до исследования нельзя утверждать. Может быть брак компонентов, например. Но дело точно не в настройках и ПО.
