If you want your USB keyboard to work in loader you need to enable "USB
Legacy" in the BIOS.

FreeBSD can only handle input from one keyboard at a time. By default the
first keyboard attached wins, which is atkbd.  You have a few options:

1. Edit /boot/device.hints and remove the hint.atkbd.0.flags line, reboot,
and unplug the PS/2 keyboard before the kernel starts. Unless your BIOS
fakes up a keyboard it should keep atkbd0 from attaching and therefore let
the USB keyboard take over kbd0.

2. Add a line to /etc/usbd.conf that calls

kbdcontrol -k kbd1 < /dev/console

when a USB keyboard is attached. This selects the USB keyboard as the
active keyboard. If kbd1 goes away (by unplugging the USB keyboard) it'll
fall back to the PS/2 keyboard.
