Toshiba SD-R2312 CD+(E)G

The Toshiba SD-R2312 CD-RW/DVD Combo Drive specs state that it is CD+(E)G compatible. I assumed this to be the same as CD+G (karaoke disks) compatible but it won’t read the graphics subcode and CDRWin shows no CD+G capability for this drive.

What does the (E) mean and can someone provide a firmware release to enable CD+G playback?

Thanks all.
