C#如何使用LibUsbDotNet实现USB通信的示例详解

本篇文章基于LibUsbDotNet。

　　1. 下载并安装 LibUsbDotNet 安装文件。

　　2. 运行Filter Wizard, Install a device filter。 安装需要通信的usb设备。

　　3. 建一个简单的控制台项目，进行测试, 下图为打印需要通信设备的信息。

PrintUsbInfo

 public static void PrintUsbInfo()          {              UsbDevice usbDevice = null;              UsbRegDeviceList allDevices = UsbDevice.AllDevices;                Console.WriteLine("Found {0} devices", allDevices.Count);                foreach (UsbRegistry usbRegistry in allDevices)              {                  Console.WriteLine("Got device: {0}\r\n", usbRegistry.FullName);                    if (usbRegistry.Open(out usbDevice))                  {                      Console.WriteLine("Device Information\r\n------------------");                        Console.WriteLine("{0}", usbDevice.Info.ToString());                        Console.WriteLine("VID & PID: {0} {1}", usbDevice.Info.Descriptor.VendorID, usbDevice.Info.Descriptor.ProductID);                        Console.WriteLine("\r\nDevice configuration\r\n--------------------");                      foreach (UsbConfigInfo usbConfigInfo in usbDevice.Configs)                      {                          Console.WriteLine("{0}", usbConfigInfo.ToString());                            Console.WriteLine("\r\nDevice interface list\r\n---------------------");                          ReadOnlyCollection<UsbInterfaceInfo> interfaceList = usbConfigInfo.InterfaceInfoList;                          foreach (UsbInterfaceInfo usbInterfaceInfo in interfaceList)                          {                              Console.WriteLine("{0}", usbInterfaceInfo.ToString());                                Console.WriteLine("\r\nDevice endpoint list\r\n--------------------");                              ReadOnlyCollection<UsbEndpointInfo> endpointList = usbInterfaceInfo.EndpointInfoList;                              foreach (UsbEndpointInfo usbEndpointInfo in endpointList)                              {                                  Console.WriteLine("{0}", usbEndpointInfo.ToString());                              }                          }                      }                      usbDevice.Close();                  }                  Console.WriteLine("\r\n----- Device information finished -----\r\n");              }          }

调用

public static void Main(string[] args)          {              PrintUsbInfo();                // Wait for user input..              Console.ReadKey();          }
