The Fresco Logic xHCI (USB3) Root Hub is a driver for the USB 3.0 (Universal Serial Bus 3.0) host controller produced by Fresco Logic, a company that manufactures USB 3.0 controllers for various hardware devices. The xHCI (eXtensible Host Controller Interface) is the specification used for USB 3.0 and later USB versions, allowing faster data transfer speeds compared to USB 2.0.

If you are using a system that has a USB 3.0 controller based on Fresco Logic hardware, you will need the Fresco Logic USB 3.0 driver (often labeled as "Fresco Logic xHCI USB3.0 Root Hub driver") to enable proper functionality of the USB 3.0 ports, ensuring devices connected to those ports work as expected.
