網上C#USB通訊的資料比較少, 基本上都是基於LibUsbDotNet 和 CyUsb, 關於印表機裝置的還有一個OPOS。
本篇文章基於LibUsbDotNet。
1. 下載並安裝 LibUsbDotNet 安裝檔案。
2. 運行Filter Wizard, Install a device filter。 安裝需要通訊的usb裝置。
3. 建一個簡單的控制台項目,進行測試, 為列印需要通訊裝置的資訊。

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"); } }
