用HID类型开发USB设备，有兴趣的朋友可以改为VC，BCB代码。-Use HID design USB device

用ＵＳＢ进行数据采集有明显的优越性，　该程序是ＵＳＢ数据采集的界面程序，配合固件程序可以行成完整的数据采集系统．-use USB data acquisition are obvious advantages, The procedure is the USB interface data collection procedures, firmware can tie into a complete line of data acquisition system.

一个VFW的视频捕捉系统，适用于标准usb接口的视频流的显示，在Vc中实现，可以很好的进行移植。-A VFW video capture system, the standard usb interface for video streaming of the shows that Vc to achieve, can be a good transplant.

vc环境下编译的一个与USB端口进行通讯的驱动程序，初学者应该看一看。-vc environment compile a USB port to communicate with the driver, beginners should take a look at.

High volume USB 2.0 devices will be designed using ASIC technology with embedded USB 2.0 support. For full-speed USB devices the operating frequency was low enough to allow data recovery to be handled in a vendors VHDL code, with the ASIC vendor providing only a simple level translator to meet the USB signaling requirements. Today s gate arrays operate comfortably between 30 and 60 MHz. With USB 2.0 signaling running at hundreds of MHz, the existing design methodology must change.

这个程序用180行C代码就能够读取FAT16文件系统U盘的根目录,可以看到根目录下的文件 名,并可显示 首文件内容,不过,该程序很不严谨,也没有任何错误处理,对U盘兼容性较差,只是用于简单试 验,作为参考. 这个程序可以支持WINDOWS按FAT16格式化的U盘,因为程序精简,所以只兼容超过50%以上的U 盘品牌,如果换 成CH375A芯片则兼容性可提高到85%,当然,如果使用WCH公司的子程序库或者正式版本的C源 程序兼容性更好-this procedure with 180 OK C code can read FAT16 file system drives the root directory, we can see the root directory under the file name, would show the first document, but the very stringent procedures, and there is no error handling, the U-poor compatibility, but for the simple test a post-mortem as a reference. this procedure can be supported by Windows FAT16 formatted U disk, because the procedure is streamlined and therefore only compatible with more than 50% of the U-brand, if chips were replaced CH375A compatibility can be increased to 85%, if the company"s use of WCH Subroutine Library or an official version of the C source better compatibility
