756 Do the Sonnet USB 2.0 or USB 3 cards support the Apple SuperDrive?Apr-02-22
None of Sonnet's Cards with USB 2.0 or USB 3 (either Type A or Type C) ports support the Apple SuperDrive. You must use a built-in USB 2.0 or 3.0 port on your Mac.

According to http://support.apple.com/kb/HT5630, "The Apple USB SuperDrive is compatible with Mac models from 2008 and later that don't have a built-in optical drive."

1099 What makes Sonnet USB 3.2 Cards more reliable than other USB 3 cards?Apr-02-22
The uniqueness of Sonnet USB 3.2 products is each USB port has a USB power switch (MOSFET) that manages and monitors the current flow of the USB port. The USB switch limits the current draw when a new USB device is connected minimizing the voltage droop of the main USB 5V power rail, thereby protecting devices connected to other USB ports from going offline because of port power droop. The USB switch is also a very effective current limiter that does not degrade over trips the way a resettable poly-fuse would.
