NIOS USB Keyboard App ?

Is there an easy (... or known) way to add to a NIOS device some USB Keyboard functions (standard 101-key USB Keyboard accepted by any USB HID class driver) ? I guess its a low-speed USB 1.1 ...

So yeah, thanx for your fast answer. I did some googling and indeed found some (non-PLD) devices used for that kind of application.

It´s indeed a USB 1.1 low speed client job using the "HID mode" - so that would be the hardware IP part and shouldn´t be too hard to find.

The other thing is the software that "emulates" a USB keyboard device - I found some 8051 code that seem to do that, maybe I can

adapt this for NIOS. PS2 is no option because I need the USB power from the host (-PC) to source my "NIOS-Keyboard" ...
