Microsoft Windows is designed to detect the identity of devices connected to the USB ports on your computer. This ability is important for the operating system to install the appropriate drivers and software for your device, and for allowing the computer to use the functions of the device as intended. You can see all devices connected to the USB ports in the Devices and Printers window, and you can scan the USB hubs for individual device information through the Windows Device Manager.
