Hi, many hardware cannot manage USB keyboards without it present at boot.
because bios or equiv doesn't enable the port so the OS (whatever it is)
cannot use it.
That"s exactly why I cannot accept usb-KVM creator existance he should die, his
family
should die, his pet should die :D :D
but usb-KVM should really be forbiden forever & all over the universe & other
parallel universes
in past & future
a solution could be to have an usb-test device connected to garantee usb is
enable
even if kvm is on another device.
