Modem 3G HUAWEI E176 Mobile Broadband - Cannot open /dev/ttyUSB0: No such

[wendelrj]

Fala Galera,

Comprei o modem 3G HUAWEI E176 Mobile Broadband desbloqueado no Centro do Rio de Janeiro. No Windows ele funcionou direitinho, mas no ubuntu 12.04, ele não funcionou nem com reza braba!!! No meu caso, como estou no laptop, prefiro usar o XFCE e estou usando o Xubuntu 12.04.

Fiz vários procedimentos, mas nada ainda. Vocês podem me ajudar?

1° Procedimento feito:

Fui configurar "banda larga móvel" em "editar configurações de rede" porém vi que o sistema não reconhece meu modem.




Tentei então o "wvdial", mas para saber se o modem estava na porta dev/ttyUSB0

rodei os dois seguintes códigos:

Código Selecionar Expandir

$lsusb


O resultado foi esse:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 011: ID 0685:2000  

Código Selecionar Expandir

dmesg

O resultado foi esse:

[ 3641.344109] StaRateAdaptive87SE(): update init_gain to index 2 for date rate 36

Pelo que dá para ver no arquivo, o xubuntu 12.04 está detectando o modem 3g como usb-stirage scsi.

Mesmo assim, editei o arquivo /etc/wvdial.conf como o seguinte:

Código Selecionar Expandir

[Dialer 3g]
Modem = /dev/ttyUSB0
Baud = 921600
DialCommand = ATDT
Check Def Route = on
FlowControl = Hardware(CRTSCTS)
Username = vivo
Password = vivo
Phone = *99#
Stupid mode = 1
Auto Reconnect = off
Auto DNS = on
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2
Init3 = AT+CGDCONT=1,"IP","zap.vivo.com.br"
ISDN = 0
Modem Type = Analog Modem

E quano rodei o código

Código Selecionar Expandir

sudo wvdial 3g

Dá o seguinte erro:

--> WvDial: Internet dialer version 1.61
--> Cannot open /dev/ttyUSB0: No such file or directory
--> Cannot open /dev/ttyUSB0: No such file or directory
--> Cannot open /dev/ttyUSB0: No such file or directory

Então galera, alguém tem como me ajudar.
Tô ficando desesperado.
Tô começando a achar que esse modem é falsificado ou sei lá...

Veja as fotos do meu modem:










Abraço a todos!

Porque não tentas pelo gestor de ligações do ubuntu

Olá wendelrj,

Poderia postar a saída do comando "lsusb" antes e depois de conectar seu modem?

[wendelrj]

#dmesg

zekkrj,

Aqui vai o lsusb

Antes de espetar o modem:

Código Selecionar Expandir

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub


E depois de espetar o modem:

Código Selecionar Expandir

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 007: ID 0685:2000 

Aqui, aparentemente a reconhecimento de alguma coisa, mas meu modem é um Huawei E176 e não um "2000" como foi reconhecido.

Se puderem me ajudar. Abração.

Eu tenho um modem da kanguru da optimus portugal que é um Huawei E173S e no linux usei sempre o gestor de conectividade e nunca tive qualquer problema

Seria bom executar o comando "sudo update-usbids" pra atualizar a referência desse dispositivo. Tem que estar com uma conexão internet ativa.

Notei pela saída do seu "dmesg" que o usb_modeswitch não foi ativado ao espetar o modem. Ele está instalado?
