Thanks for a thorough problem report. What version of udev and Linux kernel does your system use? (Alternatively, is there a URL that lists package versions for CentOS, similar to http://packages.debian.org/nut?) Could you please run udevd in debug mode while plugging in the UPS? This message shows what happens when udev properly detects the UPS and changes permissions on the /dev nodes: http://article.gmane.org/gmane.comp.monitoring.nut.devel/6558 -- Charles Lepple clepple@gmail _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
