Easy..hmmm...no.
Depending on your quantity and requirements I guess. You can get free IP from
www.opencores.org for USB.
I would say that if you have only a few units to build to rather go for a
ps2 keyboard (also easy IP to implement).
I am just thinking of all the trouble you are going to have to face writing a USB master interface to read the keyboard. BUT if you are going to do this for a mass produced product then go right ahead. USB is the face of the future. PS2 will die out soon.
BTW. If you find an easy solution for USB keyboard and/or mouse let me know as well.
