Are you sure that although you might have FW- >drives you have not attached them via USB? FireWire drives don't attach via USB. Though she may have USB drives connected to a USB hub. Just about every FireWire hub that I know of has the option of being run self-powered via an AC adapter. Here are a few examples of FireWire hubs: <http://www.macmall.com/macmall/shop/detail.asp?store=macmall&source=zwb121 66&dpno=104355&adcampaign=email,zwb12166&wt.mc_id=zwb12166> <http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo =1645478&CatId=403> and my favorite: FireWire Dino! http://www.charismac.com/Products/firedino/ All of these FireWire hubs have the option of being self-powered via an AC adapter.
