The symbols ought to indicate the type of port. See this image:

USB symbols

If it has the SS it's a USB 3 port (often blue)
If it only has the hub (base USB logo) it's a USB2 port
If it has the lightning symbol it's a USB + charging (should be on when the device is powered off/slumbering) (often yellow)
If It has the letters PD it's a Power Delivery USB 3 port which may be able to supply more power.

Be aware that there may be more USB hubs in you device manager, especially on laptops. Webcams, Keyboards and touchpads, as well as biometric sensors and keycard readers, and SD card readers are also USB, and may be connected to an internal USB2 hub without any external ports...
