leia no seu syslog:
- o dispositivo parece emular uma unidade de CD que fornece drivers do Windows.
- existem dispositivos ttyACM. Você tentou / dev / ttyACM1 e 2 em vez de ttyUSB0?
Estou tentando desesperadamente conectar um dongle 3G ao Ubuntu 12.04. Infelizmente toda vez que tento conectar (usando o wvdial) eu me deparo com a mensagem Não consigo abrir / dev / ttyUSB0: Nenhum arquivo ou diretório que eu examinei / dev e não há arquivos ttyUSB naquela pasta.
Eu tentei o comando lsusb que realmente lista meu dongle
a saída do lsusb é:

O meu dongle USB 3G é o último da lista (LG Electronics)
Como faço para que meu dongle apareça em um ttyusb?
