I head a similar problem and resolved it by resetting the P-Ram.
I have set up a general dicussion https://discussions.apple.com/message/19296258#19296258
I hope this helps

Thanks for the suggestion, Brendt. I've already reset the PRAM and SMC several times to no avail.
I suppose I'd feel better if the Hardware Test had told me that the USB ports were toast, but to tell me that they're OK and not be able to revive them is frustrating.

I am living with the resets now for a week and I am really fed up with it, but it looks like there is no other work around. On the other hand it is really difficult to blow a USB port.
I hope the general discussion will bring up some ideas.
Sorry for you
