本书将着重讲解如何编写、设计一个USB外设并使之与PC通信所需的代码。本书分析透彻，易于理解，是一本关于USB的不可多得的技术参考书籍。它不仅对初学者有帮助，而且对熟练掌握USB的高级技术人员也受益匪浅。本书共分十九章，每一章针对一个核心问题进行阐述。　　本书适合于所有从事计算机软硬件开发工程师、技术人员使用。　　USB是一种易于使用的计算机外设接口。但易于使用的代价是增加了开发才设计和编写USB设备程序的复杂性。本书全面讲述了USB设计与开发相关的知识。　　内容包括：如何在项目中使用USB接口。如何选用外设控制器芯片。如何在VB应用程序中访问USB外设。如何编写因件代码使外设与PC通信。如何选择电源以及传输类型、人机接口设备（HID）的接口、USB信号和编码等。 -err

USB设备端固件程序,枚举部分是全部程序的基础和重心,只有主机对设备枚举成功后,主机才能和设备进行正常的通信 USB的枚举过程分为4个状态. 1.接入态 v主机检测到USB设备插上,击活端口,并发送复位命令(保持10ms) 2.默认态 v主机使用默认地址读取设备描述符 (GET_DESCRIPTOR) v主机分配给设备一个总在线的唯一地址 (SET_ADDRESS) 3.地址态 v主机从新的地址获取设备描述符(GET_DESCRIPTOR) v主机获取所有设备的配置描述符(GET_DESCRIPTOR) 4.配置态 v主机设置描述符(设备,配置) (SET_CONFIGURATION) v主机读取配置状态(可选) (GET_CONFIGURATION) v主机读取接口状态(可选) (GET_INTERFACE) -USB device-side firmware, enumerate all part of the foundation and focus of the procedure, only the host of equipment after the successful enumeration, the host and equipment in order to engage in normal communication USB enumeration process is divided into four status. 1. Access state v host detected USB devices plug in, hit live ports, and send the reset command (to maintain 10ms) 2. default state v Use the default address of the host to read device descriptor (GET_DESCRIPTOR) v host assigned to the equipment of a total online only Address (SET_ADDRESS) 3.
