Made the upgrade to Mountain lion when it came out, but since the upgrade I have noticed something occurring when my laptop goes to sleep be it idling or me putting it in a sleep mode, when I go to wake the laptop almost every time anything hooked into the USB ports don't respond and remain dormant as if the laptop was still in a sleep mode.
Example one of the places I hook my Mac up has a wired USB keyboard, and a USB to VGA monitor connector which doesn't respond when I wake the laptop. Or another place where I have 2 USB Monitor connections, a USB based harddrive toaster. All of which stop responding after the laptop sleeps. I have to pull the USB's out and plug them back in to make them work again and only after I wake the laptop.
So I am wondering is there some new power settings I am missing somewhere, that don't turn the USB on after idle? Everything worked just fine prior to the Mountain Lion Upgrade so I know its nothing to do with that.
