Unknown USB Device, Device Failed Enumeration Error on Windows 11 / 10 Fix

After having used USB devices for a long time now, it is known that when you insert a USB device into a Windows PC, the drivers that are required for the USB are first installed and then the USB device is visible in File Explorer from where it can be accessed. Whenever any hardware device is connected to a Windows PC, a driver is needed that helps to communicate with the device. However, Windows cannot recognize the hardware device if the drivers are corrupted. One such error that is seen when using a USB device on a Windows computer is the Unknown USB Device (Device Failed Enumeration) Error.

USB Enumeration is the process of recognizing a USB device when it is connected to a host device. As soon as the USB device is inserted into the host device, its type is detected and the required drivers are loaded. When the USB Enumeration doesn’t work, the connected USB device is not recognized by the host, and the above error message is seen by the user in the Device Manager’s Universal Serial Bus Controller node.
