If only a few people could just say "I have this particular USB keyboard and it works for me", that would already be super-helpful. I just can't spend all my salary trying to guess which keyboard would work with my PICOZX. :)
I think it is more an issue with USB hubs than the USB keyboard not being supported. IF it helps, I use one of those mini wireless keyboards that can be found on heebay for around $10.
