LG K410 — как решить проблемы с usb-модемом на Ubuntu Mate 16.04 x64?

Question

[serega_chem]

После включения на LG K410 режима usb-модем устанавливается соединение, которое пропадает через ~15 секунд. При этом модем все ещё виден системой

serega@serega-work:~$ ls /dev/ttyACM*
/dev/ttyACM0

serega@serega-work:~$ lsusb

Установил wvdial, ниже приведен wvdial.conf. Вызов sudo wvdial к подключению не приводит

usb_modeswitch -H тоже не помогает

usr/share/usb_modeswitch/1004:61fe
DefaultVendor=0x1004
DefaultProduct-0x6300
    
TargetVendor=0x1004
TargetProduct=0x61fe

serega@serega-work:~$ usb_modeswitch -H
No default vendor/product ID given. Abort

P.S.: При подключении к ноуту на Xubuntu 14.04 подобных проблем не выявлено

В файл /etc/network/interfaces добавляем

auto enp0s29f7u6i3
iface enp0s29f7u6i3 inet dhcp

и перезапускаем сеть

sudo service networking restart
