    ID mismatch


    I have just plugged in a Mobidata EDGE modem. Here is my lsusb output.

    shehab@Rupsha:~$ lsusb
    Bus 003 Device 001: ID 0000:0000
    Bus 002 Device 002: ID 10ce:ea6a
    Bus 002 Device 001: ID 0000:0000
    Bus 001 Device 001: ID 0000:0000

    In h t t p s : / / fedorahosted . org / hwdata/export/9fe002b2873ddc29b8c01768f9b93095012c3491/usb.ids, it says

    10ce Silicon Labs
    ea6a MobiData EDGE USB Modem

    But in the first post of this thread, it says

    { USB_DEVICE(0x10C5, 0xEA61) }, /* Silicon Labs MobiData GPRS USB Modem */

    The modem is not detected now. What should I do?

    You need to read up on 'how to re-compile the linux kernel' for your system. You will need to download the kernel source code and change cp2101.c so that it includes your new device ID. Compile the kernel and boot it - and your device will attach to the appropriate module now. Make sure you 'modprobe cp2101' to load the module. And check 'dmesg' to see what the kernel does when you plug in the device.

    Good luck.
