FWIW I have this User is member of group operator /etc/rc.conf contains: devfs_system_ruleset="devfsrules_common" /etc/devfs.rules contains: [devfsrules_common=7] add path 'ad[0-9]*' mode 666 add path 'ada[0-9]*' mode 666 add path 'da[0-9]*' mode 666 add path 'acd[0-9]*' mode 666 add path 'cd[0-9]*' mode 666 add path 'pass[0-9]*' mode 666 add path 'xpt[0-9]*' mode 666 add path 'ugen[0-9]*' mode 666 group operator add path 'usbctl' mode 666 add path 'usb/*' mode 666 add path 'lpt[0-9]*' mode 666 add path 'ulpt[0-9]*' mode 666 add path 'unlpt[0-9]*' mode 666 add path 'uscan[0-9]*' mode 666 add path 'usb/4.2.[0-9]' mode 666 group operator ...and I mount manually via a short script. camcontrol devlist | grep FUJIFILM > /dev/null 2>&1 if [ "$?" -eq "0" ]; then dev=`camcontrol devlist | grep FUJIFILM | grep -o 'da[0-9][0-9]*'` if [ `df | grep $dev | grep -o 'da[0-9][0-9]*'` ]; then echo Camera already mounted else mount -t msdosfs /dev/${dev}s1 /home/dave/camera echo Mounted Camera to ~/camera as /dev/${dev}s1 fi else echo Camera not plugged in fi That's probably a rubbish script, but it works for me. I should probably go back and re-visit devfs,rules and limit the access a bit and/or get around to sorting out devd to automount it.
