The driver is part of the chipset driver package that helps your computer's motherboard communicate with the USB controller, specifically the Enhanced Host Controller Interface (EHCI). EHCI is responsible for managing USB 2.0 devices and ensuring that your computer can interact with USB peripherals such as keyboards, mice, external drives, printers, and more.

If you are seeing this driver listed in your device manager or somewhere in your system, it means the driver for the Intel USB 2.0 EHCI controller needs to be properly installed or updated. Without the correct driver, you might experience issues like USB ports not functioning properly or not recognizing devices.
