hi a friend's 17" powerbook has a broken firewire 400 port. can she use her isight on the firewire 800 port with an appropriate cable (fw 400 to 800 from belkin for ex.)? if it works for drives, it should work for the isight too, no? thanks alexandre :: 17" 1.5ghz powerbook / 1.5gb / 80gb / X.4.4 ::
