Worth noting that these won’t work with the usual garden variety USB-C hubs sporting USB-A ports; instead, you need to use an adapter as opposed to a hub[0] - maybe because of power issues? Source: I have a SuperDrive and have experienced this first hand on a USB-C-only port Mac.

Correct, the SuperDrive requires 5V at 1.6A while most hubs only provide the standard 5V at 1A. Any fast-charging USB-A port will work though and that are hubs that support that.
