Подключаем Debian к интернет через usb модем Huawei E3531i
Важно! USB модем это устройство с 2 состояниями. Вначале оно определяется как cdrom, далее переключается в режим модема. Принцип работы такой, что после переключения в режим модема в режим cdrom его не вернуть.
Подключаем Huawei E3551i
Это устройство не модем в привычном понимании, USB это роутер, с веб интерфейсом. После поключения проверим как определилось устройство:
# lsusb
...
Bus 001 Device 003: ID 12d1:1f01 Huawei Technologies Co., Ltd.
...
У устройства есть идентификатор производителя (vendor id) 12d1и идентификатор устройства (product id) 1f01.
В этом режиме устройство подключено в качестве cdrom. usb storage. Посмотрим информацию детальнее.

Для того, чтобы перевести устройство в режим модема необходимо знать строку инициализации и воспользоваться утилитой usb_modeswitch.
Переведем устройство в режим модема.
# usb_modeswitch -I -W -v 0x12d1 -p 0x1f01 -M 55534243123456780000000000000a11062000000000000100000000000000
Taking all parameters from the command line
* usb_modeswitch: handle USB devices with multiple modes
* Version 1.1.4 (C) Josua Dietze 2010
* Based on libusb0 (0.1.12 and above)

Устройство сменило идетификатор с 0x1f01 на 0x14dc, то есть переключено. Создадим файл конфигурации чтобы переключение происходило автоматически.
# cd /etc/usb_modeswitch.d
# nano 12d1:1f01

CheckSuccess=20
Теперь можно переключать устройство следующим образом:
usb_modeswitch -c /etc/usb_modeswitch.d/12d1\:1f01
Важно! Данную модель невозможно подключить как модем и в списке виртуальных консолей не будет /dev/ttyUSBx. Так что нет смысла использовать /sbin/modprobe usbserial vendor=0x12d1 product=0x14dc
