at_keyboard isn't even supposed to handle usb keyboards. Only AT ones. You need usb_keyboard and hci driver

The 'AT_keyboard' module was implemented for changing keyboard-layout, as I understand the grub manual. I embedded an non-US-keyboard layout in grubx64.efi bootloader as memdisk with all needed modules and grub.cfg included.
I am testing in uefi-amd64 with Grub 2.02 & 2.04 (Linux Mint 19.3, Debian 10 & Manjaro 20):

- terminal_input --append at_keyboard -> both inputs are active
- the embedded kbd-layout just works for my internal notebook
  keyboard
- the plugged USB-keyboard in my notebook just uses the standard
  console US-keyboard layout
- I tried the the same setting for two PCs with USB-keyboards ->
  just the standard console with US-layout is working, if I change
  'terminal_input at_keyboard' via grub-shell => USB-keyboard is
  not responding anymore

By the way the USB-keyboards work in UEFI menus and settings without any problems.

It seems 'at_keyboard' has problems with handling USB-keyboards.
