Stuff goes through the whole cam device chain if you're using the cd* devices, 
so you'll have to adjust permissions for the corresponding xpt* and pass* 
devices just like you would with scsi drives.

Example devfs.conf snippet (this is suitable for members of group operator):

# Allow cdrom user access
perm    cd0     0660
perm    cd1     0660
perm cd2 0660

# Allow SCSI passthrough/transport user access
perm    xpt0    0660
perm    xpt1    0660
perm    xpt2    0660
perm    pass0   0660
perm    pass1   0660
perm    pass2   0660
