This should "just work", and it works pretty well on my various
systems, though I haven't specifically tried USB on my Mac with USB2.

Can you post the messages you get when you plug the reader in? The
device should appear to attach to uhub3 (the one attached to ehci, the
high-speed controller), and if it isn't a high-speed device, there
should be a handoff to one of the other hubs.
