I wonder how MacOS X handles device permissions.  This smells like a
permission problem to me: all the generic stuff to find out about the
devices works (using the control endpoint), but actual data transfer
(using the bulk endpoints) doesn't.

Does it work if you run it as root (e.g. through sudo)?
