O modem 3G problemático é um K3765.

Como dar vida a ele? lsusb:

Bus 002 Device 012: ID 12d1:1465 Huawei Technologies Co., Ltd.

Ubuntu 10.04

    

Answer 1

Eu acredito que o problema que você está tendo é porque o Huawei K3765 usa "mode-switching" USB para dizer ao dongle para parar de ser um drive de CD (onde estão os drivers do windows) e ser apenas um modem 3G. p>

Se eu estiver certo, basta instalar o programa usb modeswitching e ele deverá funcionar automaticamente:

sudo apt-get install usb-modeswitch

Agora, desconecte o modem e conecte-o novamente.

Se isso funcionar, o kernel do linux tem o básico para trabalhar com o seu modem.

Siga as etapas em Como conecto-me à Internet com um modem "Huwaei Ec1260"? para configurar as coisas.
