Hi,
to make it simple, even if it can act as master, it requires to be
powered, like a gadget.
So you need "something" like a modified or special hub (somebody posted
a couple of monts ago about a german webshop selling this sort of hub)
that can feed power to both sides.
Therefore, unless your HD can act as a power source (unlikely, imho, but
check its specs) you still need that sort of hub.


Cheers,
           Igor
