    The easiest way I know of is to plug in a device that is explicitly a USB3 device. If the port does not support USB3 speeds, you will get a message saying that the device could operate faster if...

    Even though the linked question is for Windows 7, most of the info there applies to Windows 10 as well. This could be considered a duplicate of that question.

  • @JeffZeitlin - They are in fact multiple duplicates. Given this question received a question that indicates the same information as an answer to the duplicate I have no hesitation to close it as a duplicate

  • No Problem in closing, but why my ports are in black color.

  • @Mongrel - The color of the plastic is not actually relevant; it's common to use it as an indicator, but it's not mandatory. If your laptop's manufacturer was trying to cut cost, they may have chosen to not use multiple colors of plastic for the USB ports.

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...
