What is AMD Root Hub (xHCI) Driver?
The AMD Root Hub (xHCI) driver is a part of the driver package that supports AMD's USB 3.0 (or USB 3.1/3.2) host controllers, particularly the eXtensible Host Controller Interface (xHCI). The xHCI standard is used to manage USB 3.x devices, enabling faster data transfer rates compared to USB 2.0.
The AMD Root Hub refers to the root hub driver, which is responsible for controlling the communication between the system's USB 3.x ports and the operating system. The term "Root Hub" is used in the USB architecture to denote the main interface that connects the USB controller to the rest of the system.
When you install the AMD Root Hub (xHCI) driver, it allows Windows to properly detect and manage USB 3.x devices, ensuring full functionality of high-speed USB peripherals such as external hard drives, flash drives, printers, and other USB 3.x devices.
