II discovered a very interesting anomaly with my mid-2009 13". I plugged my ipad in to syncs and charge, and the ipad said, "not charging." some research on the net yielded information that the iPad requires a higher powered USB port, which all late model macbooks have... All except mine apparently..... So, I tried the other USB port, and low and behold, the ipad started charging. So the question is, is this the design of the MBP, or do I perhaps have a sub-optimal USB port?
