C#基于LibUsbDotNet实现USB通信（一）

网上C#USB通信的资料比较少，基本上都是基于LibUsbDotNet 和 CyUsb, 关于打印机设备的还有一个OPOS。

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。

using LibUsbDotNet;
using LibUsbDotNet.Main;
using LibUsbDotNet.Info;

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();
        }
