All ports directly on your Mac should be the same type. Since older USB
standards will work with newer ports , it makes little sense to include USB2
ports on a machine that supports USB3. That being said, my USB 3 hub somehow
has both USB3 and USB2 protocols running on it as indicated by System
Information.
Best wishes,
