C# USB设备监听与信息查询

USB设备插拔监听

需要重写WndProc方法，该方法可以监听系统的一些事件，我试了一下，插拔U盘有响应，但是插拔USB麦克风只会触发设备节点改变的方法

//事件代码
        private const int WM_DEVICECHANGE = 0x219; //设备改变
        private const int DBT_DEVICEARRIVAL = 0x8000; //检测到新设备
        private const int DBT_DEVICEREMOVECOMPLETE = 0x8004; //移除设备
        private const int DBT_DEVNODES_CHANGED = 0x0007;  //设备节点改变


        protected override void WndProc(ref Message m)
        {
            base.WndProc(ref m);//调用父类方法，以确保其他功能正常
            //Console.WriteLine("***************************"+ (int)m.WParam);
            switch (m.Msg)
            {
                case WM_DEVICECHANGE://设备改变事件
                    switch ((int)m.WParam)
                    {
                        case DBT_DEVICEARRIVAL:
                            Console.WriteLine("新设备");
                            int devType = Marshal.ReadInt32(m.LParam, 4);
                            Console.WriteLine("设备类型:" + devType);
                            break;

                        case DBT_DEVICEREMOVECOMPLETE:
                            Console.WriteLine("设备移除");
                            break;
                        case DBT_DEVNODES_CHANGED:
                            Console.WriteLine("设备节点改变");
                            break;
                    }
                   
                    break;
            }
        }

USB信息查询

下面是各种和USB相关的信息查询，我想实现USB插在哪个口，但是下面的信息之间毫无关联,只能通过监听USB插拔遍历总线来确定插在哪个总线上

可查询所有在用的USB总线Num：select * from Win32_Bus where DeviceID like 'PNP_BUS%'

可遍历所有的USB口：select * from Win32_USBControllerDevice

可遍历所有的即插即用设备：SELECT * FROM Win32_PnPEntity

可遍历Hub设备（Hub设备和即插即用设备不同，USB麦克风就是即插即用设备，U盘就是HUB设备）：Select * From Win32_USBHub

可遍历音频设备：SELECT * FROM Win32_SoundDevice

        private void getDevicesInfo()
        {
            ///即插即用总线信息/
            ManagementObjectSearcher mos0 = new ManagementObjectSearcher(@"select * from Win32_Bus where DeviceID like 'PNP_BUS%'");
            foreach (ManagementObject mo in mos0.Get())
            {
                foreach (PropertyData p in mo.Properties)
                {
                    Console.WriteLine(p.Name + "--------" + p.Value);
                }
                Console.WriteLine("^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^");
            }

            /USB控制器以及连接的设备/
            ManagementObjectSearcher moc1 = new ManagementObjectSearcher(@"select * from Win32_USBController where Manufacturer='Intel'");
            foreach (ManagementObject mo1 in moc1.Get())
            {
                foreach (PropertyData p in mo1.Properties)
                {
                    Console.WriteLine(p.Name + "--------" + p.Value);
                }
                Console.WriteLine("$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$");
            }

            //USB控制器以及当前与他们相关联的设备的集合//
            ManagementObjectSearcher mos1 = new ManagementObjectSearcher(@"select * from Win32_USBControllerDevice");
            foreach (ManagementObject mo1 in mos1.Get())
            {
                foreach (PropertyData p in mo1.Properties)
                {
                    Console.WriteLine(p.Name + "--------" + p.Value);
                }
                Console.WriteLine("~~~~~~~~~~~~~~~~~~~~~~~~~~~");
            }


            即插即用的某一个USB设备//
            ManagementObjectSearcher mos = new ManagementObjectSearcher(@"select * from Win32_PnPEntity where DeviceID like '%usb%mi%' and (Manufacturer like 'microsoft' or Service='usbvideo')");
            foreach (ManagementObject mo in mos.Get())
            {
                foreach (PropertyData p in mo.Properties)
                {
                    if ((p.Name == "Caption") || (p.Name == "ClassGuid") || (p.Name == "DeviceID") || (p.Name == "PNPDeviceID"))
                    {
                        Console.WriteLine(p.Name + "--------" + p.Value);
                        Console.WriteLine( "********************");
                    }
                }
            }


            某一个USBHUB谁被//
            ManagementObjectSearcher moc2 = new ManagementObjectSearcher(@"Select * From Win32_USBHub");
            foreach (ManagementObject mo2 in moc2.Get())
            {
                foreach (PropertyData p in mo2.Properties)
                { 
                    Console.WriteLine(p.Name + "--------" + p.Value);  
                }
                Console.WriteLine("+++++++++++++++++++++++++++++++++");
            }



            String Dependent = @"SWD\\MMDEVAPI\\{0.0.1.00000000}.{9A44C4D0-0BF5-4272-95FF-741DF041E4BD}";
            //SELECT * FROM Win32_PnPEntity WHERE DeviceID=" + Dependent
            ManagementObjectSearcher moc3 = new ManagementObjectSearcher(@"SELECT * FROM Win32_PnPEntity WHERE DeviceID like '%0.0.1.00000000%'");
            foreach (ManagementObject mo3 in moc3.Get())
            {
                foreach (PropertyData p in mo3.Properties)
                {
                    Console.WriteLine(p.Name + "--------" + p.Value);
                }
                Console.WriteLine("=====================================");
            }


            ManagementObjectSearcher moc4 = new ManagementObjectSearcher(@"SELECT * FROM Win32_SoundDevice");
            foreach (ManagementObject mo4 in moc4.Get())
            {
                foreach (PropertyData p in mo4.Properties)
                {
                    Console.WriteLine(p.Name + "--------" + p.Value);
                }
                Console.WriteLine("#######################################");
            }
        }
