The logs indicate that your MMC card isn't working right. Attempts to read sector 3967984 don't succeed, even though the kernel thinks the card has 3967992 sectors. You can test this yourself from the command line on the gadget; just do: dd if=/dev/mmc... of=/dev/null count=1 skip=3967984 Alan Stern -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
