USB to PS2 with arduino leonardo


I need advice if such project is doable.

I need converter from modern USB keyboard to old PS2 as some old computers does not support USB and modern USB keyboard does not work with simple converters (already tested).

So I see a need for "advanced active" USB keyboards to PS2 converter.

See this:

USB is made of Hosts and Devices. The Leonardo can natively act as a USB Device. In order to communicate with a keyboard, it you need to emulate a USB Host.

The USB Host Shield has code examples to work with Keyboards / HID devices. You don't necessarily need a Leonardo.
