I talked to him just 1 minute ago. The right approach here is to enumerate existing devices when CUPS starts up. All programs that care about devices should do that: 1) subscribe to device events 2) enumerate what's already there If everybody would retrigger the events for their devcies then the number of events would be drastically increased. Kay pointed me to this: http://article.gmane.org/gmane.linux.hotplug.devel/13925 Which is his usual reply to issues like this.
