Hello, I just did a system upgrade, and it seems that iTunes is not detecting any of my devices. I am using Mac OSX Snow Leopard 10.6.5 and iTunes 10.1 When I plug in the iPhone 4, it does start charging it, but doesn't get detected in iTunes. But when I plug in the iPod Touch (first generation), it isn't recharged or detected. I have browsed the forums and found no answer on this matter. Anyone else here who has experienced this problem or might no a solution? Help is much appreciated.
