I’ve never understood why devices only come with one port of a type when the specification is upgraded. When USB 2.0 came out, motherboards, laptops etc all came with plenty of USB 1.1 ports and then one USB 2.0 port. Then all USB ports on devices were USB 2.0.
USB 3.0 comes out and again manufacturers only put one USB 3.0 port on a device and all others are USB 2.0 ports!
USB 3.0 is much faster than USB 2.0 so if you could use it then why wouldn’t you?
