 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
