[Coco] USB keyboard interface for CoCo

[Gustavo Ranaur Schoenaker]

Allen,

I'm not an Arduino expert but, as far as I know, the USB port on Leonardo
and others Arduinos works as device only, and not as an USB host.

The Leonardo's library can be used to make an Arduino to act like a
keyboard to a computer that has an USB port, but not to accept a keyboard
and work with it

I hope you`re right and I`m wrong. Anyone can help?

Thanks,
