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.
