Perhaps I'm wooed by fad ;), anyway, I read about using PS2 mouse and keyboard should be better than using USB mouse and keyboard, perhaps to shared IRQ issues or something similar.

I didn't do it with my cards, but I guess this should work, resp. I guess you're searching for USB, because you're using a laptop? I guess there're Envy24 USB devices too and they are very cheap, but full duplex etc..
