Hi guys,


Everything was ok yesterday but right now when I connect my iPhone 4S to my Macbook Pro Retina display (I've got it yesterday) left USB it keeps connecting and disconnecting. I'm on Lion latest update.


I've tested with another cable same result. Turned off and on both MBPR and iPhone 4S twice didn't help.


No the interesting part that may help: it works fine on my PC all three USB ports. It works on right USB port of my MBPR too. I've tested the left USB port (That has a problem) with other devices. I'm writing this post with an external keyboard plugged to this port. I've tested this port with my iPod Touch and it worked fine. Only happens with my iPhone 4S and this left USB port.


Any suggestion? Is it possible that the USB port not working well? Any way to assure it's fine?


Thanks alot.


MacBook Pro (Retina, Mid 2012), Mac OS X (10.7.4)
