keyboard has a weird layout after boot

[László Lajos Jánszky]

 I have an Obins Anne Pro keyboard, which is a 60% mechanical NKRO keyboard
http://en.obins.net/anne-pro It works properly in the UEFI and in the
rescue shell when I quit the boot menu, but after FreeBSD booted up and I
got the login screen it changes layout to something weird. For example I
got "a" when pressing backspace or "w". Most of the keys stop working. I
used it on a Win7 PC for a few years, so it works fine and in theory it has
a standard US ANSI layout, at least the UEFI and the rescue shell does not
have problems with it. I tried it with FreeBSD 12.1 and KDE. I tried
another keyboard, which is a Logitech K360 and that works as expected with
102 key generic Hungarian layout. I tried all the generic models in KDE
with US layout by the Anne Pro, but had no success. I tried to disable the
KDE by commenting out "exec ck-launch-session startplasma-x11" from the
.xinitrc file, but somehow FreeBSD still boots with KDE idk why. I tried
the keyboard in a console with ctrl+alt+f3, which in theory would be the
same as booting without KDE and it had the same issue in that console too,
so I think it is not an xorg related thing, but I am not entirely sure.
Somebody suggested changing the keyboard mode to 6-KRO, but I did not find
anything about it in the manual, so probably this keyboard is NKRO only.
Any idea how to make it work with FreeBSD or what causes this problem?
