The controller ports connect to the maple bus, as does the serial port on
the back. The bus itself is not limited to 256kbit/s, only each controller
port (I assume this is to prevent what we see on a USB bus, where devices
such as camera will start hogging the entire bandwidth). I do not know
what the maximum throughput of the rear serial port is off the top of my
head, but I doubt it is 2Mbit/s (for the same reason stated above).
