|Some USB ports on your PC are USB 2.0, but others are USB 3.0 which has a faster transfer rate.|
Whenever you plug a USB 3.0 device into a USB 2.0 port you will see that message.
Plug your USB 3.0 device into a USB 3.0 port (USB 3.0 ports have a blue divider).
The USB 3.0 port will probably be on the rear panel where the power cable plugs in.
Look for one with a blue divider.
