I have USB keyboard in addition to the regular AT keyboard.
There is kbdmux0 device.

Command 'kbdcontrol -i < /dev/console' doesn't print ukbd0 at all:
# kbdcontrol -i < /dev/console
kbd1:
    kbdmux0, type:AT 101/102 (2)

So I can only tell that ukbd0 is attached by trying to remove it and not getting 'Device not configured' error, see the following command sequence.

# kbdcontrol -i < /dev/console
kbd1:
    kbdmux0, type:AT 101/102 (2)
# kbdcontrol -A ukbd0 < /dev/console
kbd1
    kbdmux0, type:AT 101/102 (2)
# kbdcontrol -A ukbd0 < /dev/console
kbd1
    kbdmux0, type:AT 101/102 (2)
kbdcontrol: unable to (un)mux the keyboard: Device not configured
