I don't understand the answers to this question:
My Acer laptop has three USB ports - two of which look similar, while the other looks like it's a bit larger but is still somehow a USB port.
My ports are of different versions (the larger one one I think is a lousier version when I plug something in it starts complaining about speed stuff). Is there anyway to swap the versions of USB port-A to port-B and port-B to port-A (so I don't have to physically shift around some stuff) ?
Is there any way to upgrade all my USB ports to 3.0 or swap the "versions" of each port?
