Here is what I did to fix USB and CD-ROM/DVD access problems.
1) Created groups “usb”/“cdrom” and added my user-id to those groups.
pw groupadd usb
pw groupadd cdrom
pw groupmod usb -m <username>
pw groupmod cdrom -m <username>
2) Added the following to the file /etc/devfs.rules:
[custom_rules=10]
add path 'da*' mode 0660 group usb
add path 'msdosfs/*' mode 0660 group usb
add path 'usb/*' mode 0660 group usb
add path 'ugen*' mode 0660 group usb
add path 'pass*' mode 0660 group cdrom
3) Activated this ruleset in /etc/rc.conf:
devfs_system_ruleset="custom_rules"
4) reboot to activate the new ruleset and rules.
