Solution 1:
The MacBook Pro internal SuperDrive uses a standard SATA connector. You should be able to use any SATA > USB cable to mount the SuperDrive externally.
It was a common modification to replace a MacBook's SuperDrive with a second Hard Drive. Those people then had the option to use the SuperDrive externally, as in the video below:
