[QUOTE="mezcalsonics, post: 1480696, member: 276698"] Hi guys, Firstly a happy holiday season to you all. The other day, while using my MacBook Pro (13", early 2012 model (non-Retina), i7) I needed to free up another USB port, so I plugged in a non-powered hub & an extra external hard drive to be told by OS X that my devices were consuming too much power & hence one had been shut down... I opened up System Information via Applications, Utilities & found that the FaceTime HD Camera, while turned off, was still being allocated it's 500m amps of power. I thought this interesting as there were no applications open that would require the camera to be available, etc. I could see that on the other USB Hi-Speed Bus that controls the Bluetooth adaptor that there was no power being used while it was switched off, even though it had been allocated 500ma of power. Why does the HD Camera use 500ma of it's allocated 500ma while switched off, while other adaptors do not use any of [I]their[/I] allocated power while switched off? Apart from being a wasted of power & battery life, this limited two USB channels are further limited by this issue... Has anyone else come across this anomaly, or is it there for good reason? Any help or feedback would be most appreciated. Cheers guys, mez [/QUOTE]
