usb-hid
发现usb_hid网上可参考的资源少，基于C#源码的就更少了，尤其是能通过验证的资源简直是没有，本usb hid源码在两三个银行用外部标准接口的硬件设备（如柜外清，条码识别，及指纹识别）测试通过了，关键是已经封装成了一个C#控件，使用时只需调用UsbLibrary.dll文件就行了，别再用那writefile了(Found usb_hid fewer resources available online reference, based on C# source code and even less, especially through the resources simply do not verify the source usb hid in two or three banks with an external standard hardware interfaces (such as outside the cabinet cleared , barcode recognition, and fingerprint recognition) test, the key is already packaged into a C# controls, just call UsbLibrary.dll file when using the line, do not use that writefile the)

DLT645-07-97
说明： 本软件包用于 DL/T 645 协议的采集与数据处理。在硬件层的移植（主要针对于串口收发数据）完成之后， 用户仅需调用一个API即可完成针对于特定协议（DL/T 1997 或 DL/T 2007）的标识符数据读取、处理与存储。使用户无需关注请求数据的封包与接收数据的解包等复杂的协议内部操作，真正做到 一键采集。(This software package is used for DL / T 645 protocol acquisition and data processing. After the porting of hardware layer (mainly for serial port receiving and sending data), users only need to call an API to complete the reading, processing and storage of identifier data for specific protocols (DL / T 1997 or DL / T 2007). Users do not need to pay attention to the complex internal operation of the protocol such as the packet of the request data and the unpacking of the received data, so as to realize the one key acquisition.)
