I have a self powered USB hub that I plug my iPod and other connecting cables into ( digital camera, PSP, etc). I also have a logitech wireless keyboard and mouse that connects wirelessly through a USB reciever. If nothing is plugged in, my fans are either off or hardly noticeable. If i plug in the powered USB hub, even without the iPod connected, the fans starts reving up and stay there. I usually plug the wireless receiver into the other USB port and the fans continue to get louder. If I then plug the iPod or a digital camera into one of the ports on the hub, they go crazy. So I ask, is this normal? It just seems weird to me to have a powered USB hub cause this because it shouldn't be drawing power from the PB and things like the digital camera and PSP don't draw power in the first place. I don't recall this problem in the earlier panther updates (10.3.3 and such), only in the last very updates did this start. It drives me crazy!!
