Game Input MultipleXer

I am throwing this out there as a thought but has it been considered to use the Mbed development board.

https://mbed.org/platforms/EA-LPC4088/

I am sure it might be able to do the whole translation of input from the keyboard through to the PS4.

Any thoughts on this?

There are many devices with two usb ports.
This one could do the work, but it is a lot of work to write mouse/keyboard/joystick drivers.

I'll have a peek. Never used the teensy board in anger yet but there is always a first.
