If this only for this USB - is it save to comment that out? I do have some trouble with mounting my flash partition.

And now I dig around - as I am not sure whether I do have a Flash or a RAM problem or a configuration issue -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
