I've had this happen on occasion (not often) with a GPS receiver used for NTP. The reason the reconnected USB device gets a different node/name is that your service is still connected to the old device node, so it can't be reused. Your service should notice that the serial device went away and exit. I'm not sure if there's a way to have udev run a script or send a signal when a device goes away. -- Chris Adams <cmad...@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
