Thread: USB <-> serial for modem

  1. USB <-> serial for modem

    Anybody used a USB <-> serial cable for a modem? Hardware flow control
    and high speeds aren't necessary, as it's mostly used for grabbing
    caller-ID data from incoming calls.

    I configured the kernel like so:

    Device Drivers --->
    USB support --->
    USB Serial Converter support --->
    USB Serial Converter support[*] USB Generic Serial Driver

    When I modprobe usb-serial I get this in the log:

    kernel: usbcore: registered new interface driver usbserial
    kernel: drivers/usb/serial/usb-serial.c: USB Serial support registered for generic
    kernel: usbcore: registered new interface driver usbserial_generic
    kernel: drivers/usb/serial/usb-serial.c: USB Serial Driver core

    What do I do now?

    I read something about I need to supply the usbserial module with the
    idVendor and idProduct of the cable; is that still correct? How do I
    find that data?

    BTW:

    root@pc:~# ls /dev/*USB*
    ls: /dev/*USB*: No such file or directory
    root@pc:~# ps ax | grep '[u]dev'

    You may need one of the other drivers. lsusb may help to identify which.

    Thanks, that was it.

    Useful tool. Much easier than what I was doing. I got:

    Bus 001 Device 005: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
    (among other things)

    so I compiled the module

    USB Prolific 2303 Single Port Serial Driver

    modprobed it, udev created the node /dev/ttyUSB0, and I'm in business.
    Not sure what'll happen next time I boot...
