    Question USB Serial device does not register a /dev/ttyUSBX, Opensuse 11.3 (64bit)

    Neotel telecoms in South Africa, USB Phone and RF modem:
    On USB connect: (all commands run as root)

    # dmesg

    # ls /dev/ttyUSB*
    ls: cannot access /dev/ttyUSB*: No such file or directory

    How can I change udev to register the serial device as /dev/ttyUSB0?

    Thanks

    With you phone attached, try issuing

    Code:
    sudo modprobe usbserial vendor=0x1d09 product=0x4000
    Then see what lsusb reports.

    FWIW, here are a couple of Ubuntu-based threads on same topic (which might give you enough ideas to get started)

    Then LINUX & Neotel Prime (2010) solution works on Opensuse 11.4, thanks a zillion, the modem now register /dev/ttyUSB0 and /dev/ttyUSB1, like it should.

    Just to issuing sudo modprobe usbserial vendor=0x1d09 product=0x4000 does not work on Opensuse.

    However the following does:
    Create a script and run as root
    #!/bin/sh
    modprobe -v option
    echo '1d09 4000' > /sys/bus/usb-serial/drivers/option1/new_id

    Dmesg returns

    Tis is the content of your PM to me:
    Hi, thanks for your help last year. I havent made much progress since I last chatted to you. I have now purchased a different broadband solution hoping that this will sort my problems and get me started on opensuse.

    Please can you help me make sense of the following;

    1. Checking the net on how to install my device (still not connected to the internet on my opensuse pc) this is what i found (dont have a clue how to do it nor what exactly it means or tries to do)

    see url (USB Serial device does not register a /dev/ttyUSBX, Opensuse 11.3 (64bit)) and below

    Create a script and run as root
    #!/bin/sh
    modprobe -v option
    echo '1d09 4000' > /sys/bus/usb-serial/drivers/option1/new_id


    2. Looking at the vendors instruction on how to install I get the following

    https://www.neotel.co.za/wps/portal/..._linux_drivers


    I really dont have a **** clue where to start with this what to download...bla bla and i desperatly want to learn linux (i am beyond frustrated but dont want to give up).

    Thank you so much for tolerating me and for your help!!
