Our discussion in irc was productive. The following works with the stock permissions.sh (without the lines for setfacl). The acl does not get set, but the scanner works. And if I unplug and re-plug the usb cable, the scanner gets the next device number, and it works! cat /etc/vdev/actions/scanner.act [vdev-action] event=add path=^bus/usb/*/[001-999] OS_SUBSYSTEM=usb OS_TYPE=255/255/255 VAR_PERMISSIONS_OWNER=root VAR_PERMISSIONS_GROUP=scanner VAR_PERMISSIONS_MODE=0664 helper=permissions.sh if_exists=run daemonlet=true -fsr _______________________________________________ Dng mailing list [email protected] https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
