Sorry, I just don't think you are correct. The ArduinoUno is based on the 
ATmega16U2 which is (also) a USB *device*. Looking at the schematics, 
there's no USB host on the board either.

Are you sure you're not getting confused with having the Arduino operate as 
a USB keyboard?!? Or a different Arduino board? The only ones I have seen 
that operate as a USB host use a MAX3412e for the host functionality.

If I am wrong, apologies, but I'd like to see the reference you're citing!

In any case, the Arduino-Leonardo board doesn't have a USB host and 
therefore can't connected to a USB keyboard/mouse.
