@tom - What likely happened was you used the wrong power bricks for one of your USB devices so you burnt the ports fuse link. To prove this get a powered USB hub and plug it into one of the non-functioning ports and then plug in a passive USB device (i.e. thumb drive) if that works you'll need to get your system to someone who can do the micro-soldering and has the replacement SMT fuse link.

Of course you still have a problem! You'll want to label each of the power bricks so you know which one goes with which device so you don't damage any other ports.
