In the "Device Manager" window, click the + (plus sign) next to Universal Serial Bus controllers. You will see a list of the USB ports installed on your computer.

◦If the port name contains both "Universal Host" and "Enhanced Host", your port is version 2.0.
◦If the port name contains "USB 3.0", your port is version 3.0.
also in the device manager, you can see if the device is working perfectly or has errors.
