Hmm? I think you may be the victim of a misunderstanding. :) JFFS2 is
a "flash memory filesystem", but your "USB Flash Memory Key" is not
one of these. See
http://www.linux-mtd.infradead.org/faq/general.html#L_mtd_vs_hdd.
Sure, the same kind of NAND Flash memory is used deep inside of your
USB key, but the layer on top of that does the wear leveling etc that
JFFS2 tries to accomplish for raw Flash memory.

ext[234]
