Grub-pc usb_keyboard keymap bug

[RV]

Hi,

Keymapping different keyboard layouts works fine for at_keyboard.

example for french keyboard:

    insmod at_keyboard
    insmod keylayouts
    keymap fr  # with fr.gkb @ /boot/grub/layouts/
    terminal_input at_keyboard

However, keympapping does not work at all with usb_keyboard.

Either the documentation does not explain how to map layout to 
usb_keyboard, or it is a real bug.

Regards.
