    Do you have a properly formatted SD card that the host would be able to recognize? You may also want to try another host PC or port.

    The kernel version you are using is quite old, I assume you are working with SDK 1.0.2? I had tried this capability before and gotten it to work, though there are far newer Linux support packages available for the OMAP3 the latest being 3.x here.

    Satheesh,

    Make sure you have formatted the SD card being used. Also try to see if you can access the SD card content locally.

    You could use the command mount /dev/mmcblk0p1 /mnt and try to access the content locally. Also to make sure the card/setup is fine, you could use a card reader and connect to PC and verify whether your card gets detected and you can access it.

    Thanks,

    Prathap.

    You are right. The kernel we are using is 2.6.22 from the SDK1.0.2.

    I tried insmoding the g_file_storage.ko with a vfat formated device file, but still, no luck. Windows xp is showing "unknown device".

    insmod g_file_storage.ko file=vfat_file stall=n

    insmod g_file_storage.ko file=/dev/mmcblk0 stall=0

    Unfortunately, for the time being, I need to get usb to work with this kernel itself.Is the process easy with newer kenel. Here is the .config of the kenel build. Is it ok for usb gadget.

    .config during kernel build .

    #
    # USB Gadget Support
    #
    CONFIG_USB_GADGET=y
    # CONFIG_USB_GADGET_DEBUG_FILES is not set
