Current protection and limiting is completely up to the card designer. The best that FreeBSD can do is getting informed if the card design allows it, but I almost never saw a card doing this. Many cards just have some kind of self healing or melting fuses, some very bad designed cards don't even have this. Either your hubs really use more power then it is allowed to or you have a broken controller card. -- B.Walter BWCT http://www.bwct.de ticso@bwct.de info@bwct.de
