You probably need to put a delay in the /etc/init.d/upsd script for
restart. Stopping a driver is an asynchronous process, which means that
the actual stopping of the driver will be sometime later. Assuming this
script looks something like

  restart)
	$0 stop
	$0 start
	;;

you'd need to sleep for a second or two between stopping and starting like

  restart)
	$0 stop
	sleep 2
	$0 start
	;;
