I use the following scripts. This /etc/usb_kbd was an improvement
version and became a topic with "-tech-jp ML" in Japan before a
little. When you use it, please do "chmod +x". And you can use
below four variables with rc.conf.
keymap_<keyboard>
keyrate_<keyboard>
keybell_<keyboard>
keychange_<keyboard>
<keyboard> is device name of an USB keyboard.
For example, when you use a "jp.106x" keymap with ukbd0, you add
keymap_ukbd0="jp.106x" line to /etc/rc.conf. And other variable are
similar, too.
However, a case to use several USB keyboards is a testing shortage.
And keyboard device will not accord with variable name of rc.conf by
order to connect an USB keyboard to.

I like b) plan, too.
