Let MindShare Bring xHCI to Life for You

The xHCI (eXtensible Host Controller Interface) for USB 3.0 consolidates support for all generations of USB Low Speed, Full Speed, High Speed, and SuperSpeed peripherals and hubs. While a standard USB controller and software interface is defined, a wide range of xHC hardware implementations and programming options are permitted to accommodate requirements of platforms ranging from embedded devices to PCs, workstations, and servers. When compared with earlier host controller models, xHCI also brings significant enhancements in the areas of platform power management, USB transaction scheduling, bandwidth management, and diagnostics/debug.

Comprehensive xHCI + Fundamentals of USB 3.0 Course Info

 Who Should Attend?

MindShare offers three standard xHCI training options. This comprehensive three-day course targets software, hardware, validation engineers and other technical people with a need to understand the details of xHCI protocol as well as the fundamentals of the USB 3.0/2.0 topologies it supports. Course content includes USB 2.0/3.0 protocol review, xHC hardware, programmer's register and memory interface, and the xHCI operational model: controller initialization, device attachment and removal, transaction management, error handling, host controller interrupts, etc.

The other two standard MindShare xHCI course options include a one-day xHCI for USB 3.0 Overview or two-day Comprehensive xHCI For USB 3.0 course without the review of USB 2.0/3.0 fundamentals. All MindShare courses may be customized to suit specific customer requirements.
