Has anyone else experienced a recurring error stating that the energy consumption of a USB peripheral is too high? I figured it to be one of those no brainer problems, but via process of elimination (plugging and unplugging my keyboard, mouse, and disabling the bluetooth unit) I have been unable to discontinue the message. Furthermore, after looking through the system profiler, the only usb port that this consuming much of any energy is this isight port but it is still consuming only its allotted 500 mA. I ran the Apple Hardware tests twice and have not discovered any hardware failure. I'm now at a loss with an error message that pops up over the top of the desktop every 30 seconds or so. I'm running 10.6.3 on a 2.4 Ghz Core 2 Duo Imac. I am out of the range of my 1 year warranty. Any advice?
