Overview
The xHCI (eXtensible Host Controller Interface) for USB consolidates support for all generations of USB Low Speed, Full Speed, High Speed, SuperSpeed, and SuperSpeedPlus peripherals and hubs. The xHCI specification defines both host controller hardware behavior and the interface used by software to manage the controller and devices below it. A wide range of hardware implementations and optional features accommodate platforms ranging from embedded devices to PCs, workstations, and servers. When compared with earlier USB host controller models, xHCI also brings significant enhancements in the areas of platform power management, transaction scheduling, virtualization, and bandwidth management.
All of MindShare's classroom and virtual classroom courses can be customized to fit the needs of your group.
