C#中WinUSB设备的识别与枚举

在C#中识别和枚举WinUSB设备，我们可以使用Windows API函数来实现。下面是一个简单的示例代码，演示了如何使用C#来识别和枚举WinUSB设备：

using System;
using System.Runtime.InteropServices;

class Program
{
    [StructLayout(LayoutKind.Sequential)]
    public struct SP_DEVICE_INTERFACE_DATA
    {
        public int cbSize;
        public Guid interfaceClassGuid;
        public int flags;
        public IntPtr reserved;
    }

    [StructLayout(LayoutKind.Sequential)]
    public struct SP_DEVINFO_DATA
    {
        public int cbSize;
        public Guid classGuid;
        public int devInst;
        public IntPtr reserved;
    }

    [DllImport("setupapi.dll", SetLastError = true)]
    public static extern IntPtr SetupDiGetClassDevs(ref Guid classGuid, IntPtr enumerator, IntPtr hwndParent, int flags);

    [DllImport("setupapi.dll", SetLastError = true)]
    public static extern bool SetupDiEnumDeviceInterfaces(IntPtr deviceInfoSet, IntPtr deviceInfoData, ref Guid interfaceClassGuid, int memberIndex, ref SP_DEVICE_INTERFACE_DATA deviceInterfaceData);

    [DllImport("setupapi.dll", SetLastError = true)]
    public static extern bool SetupDiGetDeviceInterfaceDetail(IntPtr deviceInfoSet, ref SP_DEVICE_INTERFACE_DATA deviceInterfaceData, IntPtr deviceInterfaceDetailData, int deviceInterfaceDetailDataSize, ref int requiredSize, ref SP_DEVINFO_DATA deviceInfoData);

    static void Main(string[] args)
    {
        Guid guid = new Guid("{88BAE032-5A81-49f0-BC3D-A4FF138216D6}"); // WinUSB GUID

        IntPtr deviceInfoSet = SetupDiGetClassDevs(ref guid, IntPtr.Zero, IntPtr.Zero, 0);
        if (deviceInfoSet != IntPtr.Zero)
        {
            SP_DEVICE_INTERFACE_DATA deviceInterfaceData = https://www.yisu.com/ask/new SP_DEVICE_INTERFACE_DATA();>
在上面的示例中，我们使用了SetupDiGetClassDevs、SetupDiEnumDeviceInterfaces和SetupDiGetDeviceInterfaceDetail这几个Windows API函数来获取WinUSB设备的信息。通过调用这些函数，我们可以获取WinUSB设备的路径信息等。在实际应用中，我们可以根据获取到的设备路径信息，来进行对WinUSB设备的操作。
