По работе приходится использовать usb модемы, как правило работают долго и не виснут. Но бывает когда модем нужно перезагрузить, т.к. он залип.
Решается все утилитой usbreset
Запсукается так ./usbreset /dev/bus/usb/001/070
В иделае вывод должен быть Reset successful, но не понятно перезагрузилось устройство или нет. На сервере с астериском будет сообщение
[Aug 20 15:19:47] ERROR[18338]: chan_dongle.c:414 do_monitor_phone: [dongle0] Lost connection to Dongle
— [dongle0] Dongle has disconnected
— [dongle0] Trying to connect on /dev/ttyUSB2…
— [dongle0] Dongle has connected, initializing…
— [dongle0] Dongle initialized and ready
Астериск и сам может перегрузить модем dongle restart now dongle0
Альтернативный вариант, скриптом (взят от сюда). Данный вариант выдвал ошибку ругался на grep, внес правки в него

echo "Searching for $1"

Если скрипт отработал, то в логе должно быть
