Multiple keyboards in FreeBSD

[Preston Crawford]

I'm using 4.9.

Does anyone know how to do this or if it's possible? All I can do is use 
kbdcontrol to switch from my PS/2 to USB keyboard. This is fine as the USB Keyboard in question is a word processor that I only rarely need to connect. But under Linux I could connect both at the same time, so it would be handy if I could do the same here.
