That depends on the USB Flash drive you are talking about.  Most don't
expose the raw flash chips contained within them.  So typically you'd
have to use something like block2mtd to convert the USB mass storage
device to an MTD and then put JFFS2 on top of that.

If that sounds like too much work, you can try ext3 and hope that your
USB flash drive has decent wear-leveling contained within it.
