This allows you to initialize usb_host.Port once successfully and then returns the same object as long as you pass the same arguments in. It does allow you to fix incorrect pins but not switching from one valid set to another. (It needs a reset for that.) This also moves hcd cache operations to RAM so that they don't access the cache when doing maintenance.
