In your response to the Letter of the Month in the January 2021 issue about music CDs and ripping them, you said this regarding using an Apple SuperDrive: “The Apple SuperDrive reads and writes… plugged into an USB port (obviously on newer MacBooks you’ll also need a hub to do this).”
At least on my older Macs, if I don’t plug the SuperDrive directly into the USB port, it will not work. Plugging into a powered hub (either of the two different hub brands I have) is not sufficient to get my SuperDrive to be recognized by my Macs. The disk will not get sucked into the SuperDrive.
