C#怎样运用LibUsbDotNet完成USB通讯的示例详解【C#.Net教程】,LibUsbDotNet,csharp,.net

网上C#USB通讯的材料比较少，基本上都是基于LibUsbDotNet 和 CyUsb, 关于打印机装备的另有一个OPOS。

本篇文章基于LibUsbDotNet。

　　1. 下载并装置 LibUsbDotNet 装置文件。

　　2. 运转Filter Wizard, Install a device filter。装置须要通讯的usb装备。

　　3. 建一个简朴的控制台项目，举行测试, 下图为打印须要通讯装备的信息。

援用　　

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");
            }
        }

挪用

public static void Main(string[] args)
        {
            PrintUsbInfo();

            // Wait for user input..
            Console.ReadKey();
        }
