RHEL 4 has only /proc/bus/usb; FC6 has both /proc/bus/usb and /dev/bus/usb

For the original poster: you can safely modify /etc/init.d/halt, just 
make sure that
-  you do not cut the power before unmounting all FS to which things are 
written (those with persistent storage)
- keep the modified script handy, because any update of the initscripts 
rpm will probably overwrite it
You might wish to take a look at the scripts included in FC devel 
(rawhide) rpms, they might be useful
