What was used:

  • Computer with Linux Ubuntu. (Linux 2.6.12-10-386 #1 Sat Mar 11 16:13:17 UTC 2006 i686 GNU/Linux)
  • pcmcia_cs installed (Ubuntu Brezzy Bager and Dapper Drake as it installed as default)
  • pppconfig intalled (Ubuntu Brezzy Bager and Dapper Drake as it installed as default)
  • 3G/GPRS PCMCIA card (mine is a HUAWEI E600 from OptimusKanguru)

Methodology:

In some cases the HUAWEI E600 firmware upgrade might be needed. To do so, it should used MS Windows, i didn’t found any other way to update the card’s firmware. The firmware can be downloaded from the Kanguru web site, apparently Huawei does not provide the firmware upgrade on their web site.

Step 1 – Pluging in the card:

With the card disconnected wright on the xTerminal write the fowling:

~$tail -f /var/log/messages

This will let know what is happening in the system. Now the card might be plugged in. Check the xTerminal to see the changes.
The feedback information can be one of two things:

  • Case 1: The card driver was not loaded when it was inserted. Then it should be something like this on the xTerminal:

 

[4296903.314000] hub 5-0:1.0: USB hub found
[4296903.314000] hub 5-0:1.0: 1 port detected

[4296903.555000] usb 5-1: new full speed USB device using ohci_hcd and address 2

  • Case 2: The card driver was loaded when it was inserted. Then it should be something like this on the xTerminal:

May 2 05:10:19 localhost kernel: [4295017.626000] usbserial_generic 5-1:1.0: Generic converter detected
May 2 05:10:19 localhost kernel: [4295017.632000] usb 5-1: Generic converter now attached to ttyUSB0

May 2 05:10:19 localhost kernel: [4295017.645000] usbcore: registered new driver usbserial_generic
May 2 05:10:19 localhost kernel: [4295017.645000] drivers/usb/serial/usb-serial.c: USB Serial Driver core v2.0

Note: If this is your case, go to step 3. If you are using “Dapper Drake” (Ubuntu 6.06 RC), your card should be recognized, and the serial_cs loaded when you plug in the card.

Step 2 – Loading the PCMCIA Driver

To check for the vendor and product “ID” in the file /proc/bus/usb/devices, with the purpose of loading the card driver from the Kernel. It was needed to open a new xTerminal [CTRL+SHIFT+N] and type:

Note: that the other one is occupied with the systems report, and i choose to have it running at all times

~$ sudo cat /proc/bus/usb/devices

It should print several entrances, but the only one that matters for this purpose, is the one with the card manufactures. It can be check on the Manufacturer entrance.

T: Bus=05 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=12d1 ProdID=1001 Rev= 0.00
S: Manufacturer=HUAWEI Technologies <–my card manufacturer
S: Product=HUAWEI Mobile
S: SerialNumber=HUAWEI DEVICE
C:* #Ifs= 3 Cfg#= 1 Atr=a0 MxPwr=500mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
E: Ad=81(I) Atr=03(Int.) MxPS= 16 Ivl=128ms
E: Ad=82(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
I: If#= 1 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
E: Ad=84(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=04(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
I: If#= 2 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
E: Ad=85(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=05(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms

Now it’s time to load the PCMCIA serial port driver – serial_cs .

~$sudo modprobe serial_cs

~$sudo modprobe usbserial vendor=0×12d1 product=0×1001

Note: modprobe is a program to add/remove modules from the kernel.

The vendor and the product id in the previous line is for the Huawei E600, you should use the one that you have previously written down, with “0x” in the front because it is a hexadecimal number [1].
The xTerminal where log is being printed, should have something like this:

May 1 14:09:42 localhost usb.agent[8225]: usbcore: already loaded
May 1 14:12:02 localhost kernel: [4294993.412000] usbcore: registered new drive r usbserial

May 1 14:12:02 localhost kernel: [4294993.436000] usbserial_generic 5-1:1.2: Ge neric converter detected

May 1 14:12:02 localhost kernel: [4294993.442000] usbcore: registered new drive r usbserial_generic
May 1 14:12:02 localhost kernel: [4294993.442000] drivers/usb/serial/usb-serial .c: USB Serial Driver core v2.0

Note: There are three USB ports. Mine are called ttyUSB*, but it can also be called of ttyS* (where * may be 0,1,2). The USB0 is used for ppp connection, USB2 is used for network related tasks, and USB1 doesn’t have any particular function[2].
Just to make sure, if the devices are mounted:

~$ls -l /dev/ttyUSB*

Step 3 – Configuring the network access

To configure the network access, i used pppconfig. Several other programs, such as wvdial, gnome-ppp, or others might be used, suit what is best for you. On my xTerminal i wrote down:

~$sudo pppconfig

And then i created a new connection, that i give the name “Kanguru”.
notes (check the picture):

  • I used Dynamic DNS and PAP Protocol.
  • The connection speed should be set as high as possible, i tried the recommend by Harwick – 460800 [2].
  • On the dialing mode i selected “tone”.
  • My user name was the card number, and the password was the PIN.
  • the phone number is *99***1#, and appears to be international.
  • In my case the program didn’t found the connection port, so i used the /dev/ttyUSB0 (note: the capital letters are very important)

ppp configuration utility

Step 4 – Activating/deactivating the connection

To activate the connection:

~$pon the_name_on_step_4

To deactivate the connection:

~$poff

To eject the card:

~$ sudo cardctl eject

Instead of always open your xTerminal to to eject and kill the network connection, you can simplify this action by making a script:

Open Gedit (or the favorite ascii text editor):

#!/bin/bash
#created by jose reis
gksudo -u root -k -m “Enter SUDO password to eject the PCMCIA CARD”
poff -a
sudo cardctl eject

Save as “PCMCIA-eject“, or the file name you wish, in [my_home] “~/.gnome2/nautilus-scripts“. And then change the permissions (right click on the file, and then “Properties” on the tab “Permissions”) to execute.

The script should be avaible if you right click on the Desktop, choose the scripts option, with the name you have gicen to the file, in this case PCMCIA-eject.

Note: It is important to eject the card before you remove it, if you fail to do so you may risk to damage your card.

Remarks

I saw lot’s of techniques how to configure the network, since using gnome-ppp, constructing my own wvdial.conf file by hand from scratch, etc.. But none of them worked for me, so i decide to start searching for other solutions. And this is only one solution.
I did not upgrade my firmware, because, at this time, i do not have access to any machine with MS Windows and PCMCIA card connection, but it is highly recommended by Optimus to do so.

One major problem that i am yet to solve, is every time that i reboot my laptop i have to load the PCMCIA card driver, witch is very annoying. This problem is already solved in the “Dapper Drake” (Ubuntu 6.06 RC).

Conclusions

It does not a require hard work to load a PCMCIA card 3G/GPRS connection to work. But i do not think that it is not very user friendly, the amount of information that the user must deal with is big and a bit intimidating for the majority of the computer users, allied to the fact that the providers do not support any other OS than the Microsoft OS.

The most difficult part was to activate the connection to my provider, it toke me almost a day do accomplish that. The configuration strings that i found on the Internet did not worked for me.

Of the techniques that i read, this one, i believe, is the most easy to use technique, because you do not have to change/edit/create files by hand on your system, and pppconfig is a very simple to use program. I don’t know if it works for others providers, i only know that it works for me.

    Viva,
    desde já dou-lhe os parabéns pelo artigo. Com ele consegui configurar a minha placa kanguru sem problemas.

    Contudo, gostava de saber, se me puder dizer, o que tenho de alterar para que cada vez que reinicie o sistema ele detecte os parâmetros. É que assim tenho de estar sempre a configurar a placa.

    Cumprimentos,
    Anselmo

    Olá:

    Fico feliz por este artigo lhe ter sido útil.

    Quanto ao problema de se ter de reconfigurar a placa cada vez que se reinicia o PC, é de facto um problema que, também, me aborrece. Ainda não tive tempo para encontrar uma forma de carregar o módulo serial_cs ao reiniciar o PC, até pq a minha chegada ao mundo Linux é recente e a minha expertise não é muito elevada.

    No entanto fica a promessa de em breve colocar essa informação neste Blog. Fique atento.

    Atenciosamente
    Jose Reis

  7. ergonomica Says:

    hello there:

    I’m supposing that you have installed Ubuntu 6.06, and the PCMCIA card is well mounted (check step 2 on this tutorial, for more information).
    The problem that you are experience (note that i’m “talking” with almost none information) may come from:

    1st- you made some error when configuring the connection (duble check the connection configuration): when i made my 1st connection the things that i have made wrong was:the user name and the password (DUH!). check the path to modem also.

    2nd- check by your ISP, is all is well with your connection.

    hope that i could be of some help. if this doesn’t work, contact me again.

    Olá.

    Estive a usar o teu scipt para configurar a placa Vodafone no Linux. Tentei com o novo Ubuntu, mas, nem consegui formatar os devices (um dia vou tentar entender pq).
    O Fedora Core 5 consegui instalar, mas, num sei pq, não consigo conectar-me.

    Estou já com a nova versão da placa 3.5G que atinge a velocidade de 1.8Mbits.

    Quando conecto a placa já obtenho informação diferente no /var/log/message:

    não sei pq e quando .. o modem disconecta-se…. o que achas que pode ser?
    Será da placa nova? Será do FC5 ? Mas com ele já consegui instalar à 1º com a placa antiga……

    estranho… muito estranho.

    espero que me possa ajudar.

  9. ergonomica Says:

    olá, Paulo Aboim:

    Eu nunca experimentei utilizar este metodo para configurar a placa PCMCIA, com o FC5. E também não tenho nenhuma placa 3.5g, o orçamento não o premite:(, e também pq acho que as velocidades de acesso não são muito diferentes da 3g, mas isso é contestável.

    Aparentemente a tua placa terá sido bem reconhecida pelo FC5 (pelo que vejo no teu /var/log/messages).

    Eu suponho que o teu problema (nota: já escrevi no post anterior e volta a escrever), possa ser um de dois:
    *ou configuras-te mal a os dados de acesso da placa – User name, Password, etc….a mim aconteceu-me durante tempos a fio.
    *ou é um problema da vodafone, e ai vai chatea-los, pode ser que tenhas sorte e apanhas alguem no atendimento que seja porreiro. eu a optimus houve um dia que telefonei para eles de 30 em 30 minutos e eles sempre com a mesma lenga lenga: “não damos apoio a Linux” e eu sempre com a lenga lenga “eu não quero o seu apoio, mas exijo o apoio a placa, bla bla”… até que apanhei uma alma caridosa que se dignou a tentar ajudar-me mesmo sem saber nada de linux.

    estou a escrever isto, pq eu passei exatamente pelo mesmo durante a configuração da minha placa. o modem desligava-se sem razão aparente. e foram de facto os dois problemas que detectei, e tb como os resolvi. se não funcionar, pega no Laptop de alguem que tenha windows e experimente, pode ser mesmo da placa.

    espero que tenha ajudado, sei que não é muito cientifico, mas é eficiente.

    Eu tenho DUAL-BOOT e em windows tudo funciona bem!

    As velocidades são um pouco diferentes. Acho que não consigo é ter 1.8Mbits, mas, 500Kbits é normal e isso é um pouco mais rápido que a que 384.

    Conheces alguém de lx que me possas dar o contacto para tentar usar a minha placa num linux que funcione com a placa antiga… assim posso conseguir rastrear o erro.

    tenho o meu email no post.

    A mim não me aparece a última linha no ficheiro de log:

    tail -f /var/log/messages

    ….
    May 1 14:12:02 localhost kernel: [4294993.436000] usbserial_generic 5-1:1.2: Ge neric converter detected
    May 1 14:12:02 localhost kernel: [4294993.442000] usb 5-1: Generic converter no w attached to ttyUSB2
    May 1 14:12:02 localhost kernel: [4294993.442000] usbcore: registered new drive r usbserial_generic

    E esta seguinte linha não me aparece:

    May 1 14:12:02 localhost kernel: [4294993.442000] drivers/usb/serial/usb-serial .c: USB Serial Driver core v2.0

    Eu estou a usar um Laptop da Compaq Presario 900, q teve muitos problemas com o PCMCIA (só nas versões do kernel 2.6.12 é q funciona o PCMCIA, nas versões anteriores tinhamos sempre q sesactivar a detecção/instalação do PCMCIA para podermos instalar o linux).

    Já agora, esta placa (Huawei E600) é tb usada pela Vodafone, por acaso alguem sabe se a maneira como se faz a validação do PIN é igual ao kanguru da Optimus?
    Na placa anterior q a Vodafone vendia (Fusion UMTS ) a validação do PIN era feita por comandos AT ou usando um script (GCOM) q enviava os comandos AT e o PIN automaticamente para a placa.
    Penso q aqui o problema deve ser mais do Laptop… o PCMCIA não está a funcionar como deve ser…
    Não estou a conseguir fazer o regisato na rede da vodafone.

    Obrigado

    ola pessoal!
    tenho os mesmos problemas.
    vivo no campo, nao tenho rede fixa, comprei uma placa huawei e620 do optimus-kanguru 3.5g para o laptop
    nao tenho experimencia nenhuma como linux, mas dos dias anteriores nunca gostava do windows. sou alemao e por isso installei o suselinux 10.1
    mais facil de aprender… achei.
    o meu modem kanguru funciona muitissimo bem no windows xp – apesar do muito lento – , que tenho preinstallado no meu velho thinkpad, no linux – nem pensar. o suporte de suselinux diz que nao ajuda nas installacoes dos placas 3g e nao encontrei alguma ajuda nos foruns de suselinux.
    queria saber, antes de talvez mudar pra ubuntu ou qualquer outra distribucao de linux, se e possivel de installar o modem. se nao, nao vale a pena, pq assim vou navegar na net com o opera e windows!
    obrigado pela ajuda
