Hey everyone, Here is my setup: 2009 MacBook Pro 13" Western Digital External Hard Drive (1TB w/ its own power source) Logitech Wireless Mouse 0 items plugged in USB = iSight works great with Yahoo 1 items plugged in USB = iSight will not even turn on 2 items plugged in USB = iSight works great with Yahoo Any idea why the heck the computer does this? it does not matter the order or which of the 2 USB ports I use, this happens period. i hate talking to my wife and constantly (if I have to move or something) have her reconnect to my cam because it goes down when I unplug or plug only 1 item in. ITS FRUSTRATING! Please Help!
