I agree with your first statement. I have several older USB 2.0 thumb drives which do work with a 3.0 port, they just don't work any faster than they would with a 2.0 port.

I don't think I've seen a hub like that advertised on the Apple site. Any hubs, in fact. Lots of adapters are listed, of course, for a tidy sum. I have gradually come to resent Apple's tendency to put very little "in the box" and make you search and pay for cables and adapters, etc. This iMac is my 5th Apple device, vs about 4 non-Apple devices.

This whole USB 3.1 Gen 1 and USB 3.2 Gen 2 stuff really has my head spinning. If the config of the connector is the same, plugs should be interchangeable, but they are introducing subtle difference in shape of the connector that are making some incompatible without an adapter.
