Using the device name is not suitable in my case as the PC has three USB 
keyboards and 2 USB mice connected.  All keyboard are of the same make/model.  
Same deal with the mouse.

I got the thing working with my hack for the moment.  Haven't heard a complaint 
from the people using it for several days.

You might want to try using

  Option "Name" <name of device>

instead of using 'Option "Device" "/dev/input/eventN"' in your
xorg.conf. According to the man page, 'Option "Name"' is more stable,
especially for devices that get plugged and unplugged into different
ports (and hence get assigned different eventN device nodes).

You can also specify vendor (for the vendor ID) and product (for the
product ID) if you're pretty sure of the mappings.

E.g.:

   Section "InputDevice"
     Identifier "mouse"
     Driver "evdev"
     Option "Name" "Logitech Serial Mouse" # This is just an example,
                                           # not really a device
   EndSection
