What is USB Enumeration?
USB Enumeration is the process where a host device detects the connected USB device, determines its type, loads its drivers, and defines its communication speed. The USB Enumeration is important because different USB devices communicate with the host device differently.
The USB device Enumeration ensures the host device that the connected USB device has been detected and identified properly, and is ready to use with a specific data transfer speed. If the USB Enumeration process fails, the host device does not recognize the USB device connected to it. In this case, the user encounters the following error message in the Device Manager:
