Hi Martin --

I'm suspecting an ehci(4) bug. Does the same happen if you disable ehci 
with userconf (boot -c) and use uhci instead? Some cameras are smart 
enough to fallback to compressed mode if attached to a full speed hub, 
so you will probably need 'mplayer -tv outfmt=mjpg ...' to test if it 
will attach.

Cheers,
Jared
