Hi, I'm a happy owner of a new macbook pro 13" retina.(I'm loving this machine).
The problem is:
when I plug the USB (original cable) to the left USB port, the iPhone (5S) battery charges perfectly, but when I plug it to the right side USB port, it keeps connecting and disconnecting (with that charing sound repeatedly "plum plum plum plum plum") ...
Any help? This is very annoying. And I'm worried because the computer is brand new.
