usb communication devices protocol
There are three classes that make up the definition for communication devices: the Communication Device Class,
Communication Interface Class and the Data Interface Class. The Communication Device Class is a device level
definition and is used by the host to properly identify a communication device that may present several different types
of interfaces. The Communication Interface Class defines a general-purpose mechanism that can be used to enable all
types of communication services on the Universal Serial Bus (USB). The Data Interface Class defines a generalpurpose
mechanism to enable bulk or isochronous transfer on the USB when the data does not meet the requirements
for any other class.

Universal Serial Bus Usage Tables for HID Power Devices
This document defines the communication of Power Source Devices within the Universal Serial Bus (USB)
protocol as a Human Interface Device (HID).
Various devices can have integrated hardware power control of internal components and/or batteries. The
same functionality can also be associated with devices powered from external power sources, such as
uninterruptible power supplies (UPS). In either case, status and control communication within the USB
protocol is desirable for energy conservation, reset, and/or system shutdown.

usb video class
The video function is located at the interface level in the device class hierarchy. It consists of a number of interfaces grouping related pipes that together implement the interface to the video function.

usb Audio Device Class protocol
The Audio Device Class Definition applies to all devices or functions embedded in composite devices that are used to manipulate audio, voice, and sound-related functionality. This includes both audio data
(analog and digital) and the functionality that is used to directly control the audio environment, such as
Volume and Tone Control. The Audio Device Class does not include functionality to operate transport mechanisms that are related to the reproduction of audio data, such as tape transport mechanisms or CDROM drive control. Handling of MIDI data streams over the USB is directly related to audio and thuscovered in this document.

Linux内核完全注释 内核版本0.11(0.95)
本书对 Linux 早期操作系统内核(v0.11)全部代码文件进行了详细全面的注释和说明，旨在使读者能够在尽量短的时间
内对Linux 的工作机理获得全面而深刻的理解，为进一步学习和研究Linux 系统打下坚实的基础。虽然所选择的版本较低，
但该内核已能够正常编译运行，其中已经包括了LINUX 工作原理的精髓，通过阅读其源代码能快速地完全理解内核的运作
机制。书中首先以Linux 源代码版本的变迁历史为主线，详细介绍了Linux 系统的发展历史，着重说明了各个内核版本之间
的重要区别和改进方面，给出了选择0.11(0.95)版作为研究的对象的原因。另外介绍了内核源代码的组织结构及相互关系，
同时还说明了编译和运行该版本内核的方法。然后本书依据内核源代码的组织结构对所有内核程序和文件进行了注释和详细
说明。每章的安排基本上分为具体研究对象的概述、每个文件的功能介绍、代码内注释、代码中难点及相关资料介绍、与当
前版本的主要区别等部分。最后一章内容总结性地介绍了继续研究Linux 系统的方法和着手点

汇编 语言 Assembly Language chm版本
《汇编语言》(Assembly Language)是计算机专业中一门重要的基础课程，是一种面向机器的低级语言。它依赖于硬件，能通过巧妙的程序设计充分发挥硬件的潜力。汇编语言程序产生的代码运行效率高。因此，到目前为止，许多软件系统(例如操作系统等)的核心部分仍然用汇编语言来编写。
