CH372 是一个USB 总线的通用设备接口芯片，是CH371的升级产品，是CH375芯片的功能简化版。在本地端，CH372 具有8 位数据总线和读、写、片选控制线以及中断输出，可以方便地挂接到单片机/DSP/MCU/MPU等控制器的系统总线上；在计算机系统中，CH372 的配套软件提供了简洁易用的操作接口，与本地端的单片机通讯就如同读写文件。 　　CH372 内置了USB 通讯中的底层协议，具有省事的内置固件模式和灵活的外置固件模式。在内置固件模式下，CH372自动处理默认端点0 的所有事务，本地端单片机只要负责数据交换，所以单片机程序非常简洁。在外置固件模式下，由外部单片机根据需要自行处理各种USB 请求，从而可以实现符合各种USB 类规范的设备。-err

这是来自微软的usb2.0开发包2.0，里面有一些usb开发的参考实例源代码，和相关技术文档。-this is from Microsoft"s USB 2.0 Development Kit 2.0, there are some usb development of a reference source code examples, and related technical documentation.

This example firmware is based on Microchip s USB Support Firmware. The purpose of this example is to provide a model for making a USB combination device. This mainly entails having the USB descriptors set up correctly. File usb_ch9.c contains the mouse and keyboard descriptors in the correct configuration. The main routine of this example moves the cursor in a circle and sends keyboard keycodes for the message "Microchip USB" over and over again. Some advice: Before running this firmware open a blank text document. Make sure that when you run the device/emulator that you are able to give focus to the document. The cursor will be moving in a circle so make sure you have plenty of room to click on the editor window. This will allow you to see the message "Microchip USB" without inadvertently having the message type over an existing document.-This example firmware is based on Microchip s USB Support Firmware. The purpose of this exampl
