    cale:/tmp# sysctl vfs.usermount
    vfs.usermount: 1

    in /etc/devfs.conf:
    perm xpt0 0660
    perm pass0 0660
    perm cd0 0660
    link cd0 cdrom
    link acd0 acd0c

    cale:/dev# ll cd*
    crw-rw---- 1 root operator - 4, 27 28 Dez 21:57:24 2003 cd0
    lrwxr-xr-x 1 root wheel - 5 28 Dez 21:57:40 2003 cdrom -> cd0

    Is your user in the correct group? (operator in my example)
    Note: I'm using atapicam so you should consider cd0 as acd0
