Mac Keyboard Doesn't Recognize iPhone via USB I have a new Mac Keyboard and I've successfully connected my mouse to it, however when I connect my iPhone nothing happens.  The iPhone doesn't go into a charge state and my MBP doesn't detect the iPhone.  I've tried three different cables with no difference.  Connecting directly to the MBP works fine.

Why would the keyboard support the mouse but not the iPhone?
The Mac Keyboard is a non-powered USB hub. As such, it may or may not recognize your iPhone when attached to it.  Just in case though, have you tried connecting it to the port that your mouse currently is in? Do this just to make sure you don't have a bum keyboard.
