I have a dual host setup, one of the hosts is a desktops with X570 Steel Legend motherboard.

A KVM is used to allow swithching display and keyboard between the hosts. The X570 Steel Legend host is also dual boot, GRUB menu shows up at boot time which allows to pick the OS to use.

Then problem is that when GRUB or UEFI menu are shoing the keyboard/mouse connected over KVM do not work, the BIOS just does not see them. If I connect a keyboard directly ot a USB port - everything is fine.

Is this a known problem? Is there a way to fix it if so?

TIA,
