This issue was discussed at

   https://lists.debian.org/debian-user/2014/04/msg01052.html

It would appear that on Wheezy it is necessary for '--no-auto-detect'
to be added to the apt-cdrom command to get sources.list written to.

On Jessie 'sudo apt-cdrom -d /media/usb0 add' works with or without
this option.
