USB: The Universal Serial Bus (FYSOS: Operating System Design Book 8)
Learn to program the four major USB controllers, UHCI, OHCI, EHCI, and the new xHCI, and communicate with devices attached to their root hubs, without operating system intervention. This book teachs you how to communicate with the bare hardware to request the device descriptors and then send and received data from various USB devices including USB external Hubs.
Why Read This Book
You will learn how USB works at the register-and-transfer level and how to program the four major host controllers (UHCI, OHCI, EHCI and xHCI) so you can implement bare‑metal USB hosts and drivers. The book gives practical, low‑level examples of descriptor handling, control transfers and hub management that are directly useful when building custom firmware or debugging USB controller behavior.
Who Will Benefit
Best suited for intermediate-to-advanced embedded firmware engineers, OS or driver developers, and hardware-software engineers who need to implement or debug USB host/device stacks on microcontrollers or custom hardware.
