Yes, that is a simple array which just returns a port address where
each of the UARTs should live if they are installed.  We then talk
directly to the UART and handle all the registers ourselves.  I can't
make any comment about the rest of your post because I haven't looked
at any of the usb code yet serial or otherwhise.
