USB Super Drive problem should be made clear
After days of frustration have finally discovered that an Apple USB SuperDrive will not work with a new iMac (24-inch, M1, 2021) if you're using a powered USB hub (I was using a UGreen 4-Port USB 3.0). I swapped that for a simple Anker USB-C to USB 3.1 Adapter and it worked perfectly. Shouldn't this be made clear to stop problems like this occurring?
iMac, OS X 10.11
