The answer is that Microstudio does NOT support any CDROM drives. We only identify and support CDR drives.
If you read in the Microeditor 2.315 manual under Troubleshooting Guide, you will see a topic titled
CD Recorder and CDROM drives do not appear which states that
"No CDROM (read only) drives are recognized by Microstudio2.308 and higher for CDG work."
The reason we did this is to overcome the massive customer support calls we continued to have because users CDROM drives wouldn't read CDG. Yes, the Plextor drive can read CDG, but our software does not support it.
