You shouldn't have to make any devices.  One point of the udev device 
manager in FC4 is that it creates and destroys USB device nodes as the 
devices are attached and detached.  The device created when my APC UPS
is detected is /dev/hiddev0.

A couple of other things to be aware of when configuring nut on FC:

- The FC packages for nut work with a file called /etc/sysconfig/ups.  You 
*must* include configuration information (at least MODEL and DEVICE) in 
this file.  The FC installation of nut will not work without it.  OPTIONS 
and UPSD_OPTIONS can be configured there or in /etc/ups/.  (When I first 
set up nut, I tried the standard configuration.  I finally got it working 
by fixing /etc/sysconfig/ups, but I haven't gone back to figure out what I 
don't need from the /etc/ups configs.)

- There's a USB driver bug that causes USB errors to be logged every five 
seconds when upsd is running.  That makes for constant disk activity and 
very large log files.
