Every USB port supports a particular USB specification, which determines the ports maximum data-transfer rate (speed) and power delivery when used with a USB cable and device that meets or exceeds that specification. Select USB in the sidebar, then select a USB bus on the right. For example, if you connect a USB 3 device to USB 2 port, your device is limited to USB 2 speeds, and it cant draw more power from the port than can be delivered over USB 2.
