xsane and root permissions

[BERTRAND Joël <joel.bertrand%systella.fr@localhost>]

	Hello,

	I use a venerable Agfa scanner 1236S (SCSI) on a Digital PWS500au 
workstation running NetBSD 8 (8.99.1 kernel). This scanner is known as 
/dev/ss0 and runs as expected with root privileges.

	If I try to use xsane (or sane in CLI) as regular user, xsane doesn't 
see my scanner. Of course, I have checked that permissions of /dev/ss0 
are root:staff rw-rw-rw-. I suppose I have forgotten something, but I'm 
unable to find a solution.

	Any idea ?

	Best regards,

	JB
