I suppose it was possible that it was an "exFAT" format
<http://en.wikipedia.org/wiki/ExFAT>; although, unlikely. Using a
similar stick, I am getting this output:

root: Unknown USB device: vendor 0x0781 product 0x5530 bus uhub1

Maybe yours was really just broken. There are suppose to be a flood of
counterfeit ones being pushed through various markets. Mislabeling being
the most common problem. Apparently, it is more prevalent in Europe
than the USA at present.
