    We suggest you also ask at the beagleboard forum to reach a wider audience.

    Probably not directly applicable because too many variables are involved like kernel version and if it is supported or not, about applied patches or missing ones, but you can check if next links can apply in your case or contain some useful information

    http://processors.wiki.ti.com/index.php/UsbgeneralpageLinux-v3p1

    http://omapedia.org/wiki/USB_testing

    you have the other post about read only feature, http://e2e.ti.com/support/embedded/linux/f/354/t/195527.aspx

    to make it read-only just mount USB stick as read-only in that way system cannot modify it, unless you want that the read-only feature is from PC machine but not from inside BeagleBoard, then check initial comments in next 2 files in your kernel source for more information about ro=b[,b...] and this gadget's use, it mentions some arguments when loading it,

    /kernel-3.0/drivers/usb/gadget/f_mass_storage.c
    /kernel-3.0/drivers/usb/gadget/mass_storage.c

    Just check about next note in BeagleBoard XM reference manual about using external power source,

    http://beagleboard.org/static/BBxMSRM_latest.pdf

    The board will not function until the correct power supply is used.

    If you are using the USB OTG port in the OTG or host mode, you must have an external DC supply powering the BeagleBoard.

    one link to check for Angstrom information, it contains some interesting links
