I assumed he wanted 400 to an 800 plug, which he does. 400 mini fits the 800 plug, but since he has a male plug, the adapter outlined in the third post here is what he needs.
$58 plus a FW400-FW400 cable? That's insane. A simple FW800 to FW400 cable that plugs directly into the hub would be much cheaper and all in one piece.
