See the last devfs rule here: > <http://www.freebsd.org/doc/en/articles/cups/printing-cups-configuring-server.html>; > I already added these rules. The following shows my /etc/devfs.rules <snip> [system=10] add path 'unlpt*' mode 0660 group cups add path 'ulpt*' mode 0660 group cups add path 'lpt*' mode 0660 group cups add path 'da[1,2,3,4,5,6,7,8,9]*' mode 0660 group users add path 'usb/*' mode 0660 group users add path 'usb/1.2.0' mode 0660 group cups </snip> The last line ensures the following in /dev/usb: crw-rw---- 1 root cups - 0x5f Jun 9 12:19 1.2.0 1.2.0 is where ugen1.2 is pointing at: /dev/ugen1.2 -> usb/1.2.0 All the above settings were done before I started to search for new printers or to add new printers with the web interface of cups. So no success so far. Are there any other options? My personal guess is that cups has some problems to use root peer credentials. The following error appears in the log file of cups (error_log): E [10/Jun/2014:11:35:14 +0200] [Client 14] Invalid peer credentials for "root" - got 8, expected 0! -- Met vriendelijke groeten, With kind regards, Mit freundlichen Gruessen, De jrus wah, Wiel ************************************* W.K.
