What is USB Root Hub (xHCI)?
The USB Root Hub (xHCI) driver is a system component in Windows that manages communication between your computer and USB devices connected via USB 3.0 (or later) ports. xHCI stands for Extensible Host Controller Interface, a specification used for USB 3.0 and newer USB versions (like USB 3.1 and USB 3.2). The xHCI driver enables high-speed data transfer and proper functionality of devices connected to USB 3.0 and higher ports on your PC, such as external hard drives, flash drives, printers, and other peripherals.
The USB Root Hub (xHCI) allows multiple USB devices to be managed simultaneously, providing essential support for USB 3.0's faster data speeds and power efficiency.
