5. Some people have noted that the latest xorg 7.4 requires the hal
daemon to enumerate the input devices. hal does not (yet) work with USB2
so if you find that the keyboard/mouse are not working in X then try
adding the following line to the ServerLayout section in xorg.conf

 Option "AllowEmptyInput" "off"
