Richard,

The Ben has a mini-USB (mini-B) connector, but it only works as a USB
device, not a host.

No you can only connect a USB hub to a USB host. Won't work in the Ben.

Same, the Ben can only connect to a host, not to other devices.
However, we are working on adding a USB host (probably a second, micro-AB
connector) to the Ya NanoNote (second version NanoNote). We will have some
prototypes soon, maybe in a few weeks, and we will offer them to interested
developers.

That still doesn't change anything for the Ben though, which does not have
USB host capabilities. You need to connect it to your computer to transfer
data, or via the microSD card.

If an early-access device helps you, get in touch with Mirko or Steve they
are running the program.
