Interesting. I also have a Vaio with a memory stick port, which shows
up as umass, but I don't have any media to test it with.

I'd guess there's some Sony magic having to do with the fact that the
memory stick port also has a LED indicating "there's a memory stick
installed". Some non-USB channel that the Sony-installed drivers know
about, I'm sure.

Perhaps the Linux "Sony Programmable I/O" driver has something to do
with it? See Documentation/sonypi.txt in a recent Linux tree.

FWIW, I'm using a SanDisk CompactFlash USB reader with no problems on
that Vaio.
