 # Example devd configuration file for automatically
 # loading what modules we can based on nomatch
 # events.

 # Generic NOMATCH event
 nomatch 100 {
-	action "service devmatch start";
+	action "service devmatch start '?$_'";
 };
 
 # Add the following to devd.conf to prevent this from running:
 # 	nomatch 1000 {
 #		action "true";
 #	};
 # it replaces the generic event with one of higher priority that
 # does nothing. You can also set 'devmatch_enable=NO' in /etc/rc.conf
