if the devices look like input devices to udev (ID_INPUT is set), then they
are automatically added to X. You need to blacklist them with xorg.conf.d
snippets to avoid them being added to the server.

Section "InputClass"
        Identifier "blacklist"
        MatchProduct "device name"
        Option "Ignore" "on"
EndSection
