    Problem connecting with 3G modem Huawei E367, Orange Tunisia network provider

    Dear Ubuntuers,
    I have a problem with my 3G dongle. I knew that it is not working out of the box on Ubuntu, but I purchased it 3 days ago as I am sure the community will end up with a solution. I am not a geek but I will try to describe well the issue.



    The modem is Huawei E367, purchased from Orange company in Tunisia. it seems like usb-modeswitsh recognizes it well but it does not appear in the Network manager.

    I searched on goolge and this forum for a solution, but I only foud some threads with similar problems.

    on lsusb the modem reports itself as E398
    lsusb result before mode switched
    Code:
    Bus 002 Device 011: ID 12d1:1446 Huawei Technologies Co., Ltd. E1552/E1800 (HSPA modem)
    lsusb after mode switched.
    Code:
    Bus 002 Device 012: ID 12d1:1506 Huawei Technologies Co., Ltd. E398 LTE/UMTS/GSM Modem/Networkcard
    here is the usb-modeswitch log

    two ttyUSB created, although the device has 4 interfaces. I am not sure if 4 ttyUSB should be created?


    the command usb-devices shows the device as follow:


    dmesg as below:


    I am using Ubuntu 12.04.
    any help please?

    Try Googling on "Ubuntu" and "Huweii". It may be that you have to send a string of commands from the terminal, such as :
    echo -e "ATDT*99#\r" > /dev/ttyUSB0

    Re: Problem connecting with 3G modem Huawei E367, Orange Tunisia network provider

    Thank you for you advice, I already found this in google but no luck.

    I tried sending the messages to ttyUSB0 but nothing is likely to happen. i tried the same with ttyUSB1 and i ended with an error:

    Code:
    Couldn't set tty to PPP discipline: Device or resource busy
    here is the details.

    i started reading on ttyUSB1 on one terminal window:
    Code:
    root@vostro1015:~# tr -s "\n" < /dev/ttyUSB1
    on another terminal I issued the following commands.

    Code:
    root@vostro1015:~# echo -e "AT+CPIN="0000"\r" > /dev/ttyUSB1


    Code:
    root@vostro1015:~# echo -e "ATDT*99#\r" > /dev/ttyUSB1


    Code:
    pppd ttyUSB1 115200 nodetach defaultroute noipdefault noauth lock usepeerdns
    Couldn't set tty to PPP discipline: Device or resource busy
    is there any comments?

    Update.

    this is issue is solved. i am right now posting this message using my new 3G connection.

    I restarted the procedure described above. just before invoking the pppd command, i terminated the tr command on the other terminal window. it connects like a charm.

    to summarize:
    1) insert the 3G modem, wait a moment until it is mode switched.
    2) use /dev/ttyUSB1 instead of /dev/ttyUSB0
    3) unlock the sim card with the pin number by:
    Code:
    root@vostro1015:~# echo -e "AT+CPIN="0000"\r" > /dev/ttyUSB1
    4) initialize the modem
    Code:
    root@vostro1015:~# echo -e "ATDT*99#\r" > /dev/ttyUSB1
    5) start a ppp connection
    Code:
    root@vostro1015:~# pppd ttyUSB1 115200 nodetach defaultroute noipdefault noauth lock usepeerdns
    here is the result


    May this help someone.
