Apple external CD drive. Have used it connected to Mac Mini thru a multiport adapter. external drive is USB. adapter connected as USB-C. upgraded OS on my Macs to Monterey. now get the notification to connect thru a powered USB port. I can plug into the Mac mini thru a USB A port and that worked. 2 different adapters don't work now. Bought a new Mac Book Pro 16in M1 chip. got the same pop up message. doesn't have a USB A port, just USB-C's. the change happened after Monterey; that's why I'm wondering if it is that.

Some hubs do not work with Monterey. Thus if the multiport adapter is a hub the hub may be the problem.
The USB ports (including Thunderbolt) do not provide enough power for some drives for some computers and if this is thr case a powered hub that works with Monterey may work.
I have not heard only problems with a USB-C male to USB-A female adapter, that is they always work.
There was at least another discussion on this same subject If I recall it all depends on the Mac whether it will works when directly connected with simple adapter. Some need a powered hub and that hub has to work w/Monterey.
