开放原子开发者工作坊

最近项目需要需要试试采集电脑USB 设备信息 找到了 开源 示例 代码非常好  公共库也很友好  可能知名度太低   才4star

示例图

 

 

 代码结构

 

 UsbDevicesDotNet是公共库

UsbDevicesViewer是WPF界面

别的是控制台测试

 

获取电脑所有USB设备信息 

List<UsbDevice> UsbDevices = UsbDevice.GetDevices(new Guid(UsbDeviceWinApi.GUID_DEVINTERFACE_USB_DEVICE)).ToList()

　

 设备事件

        private Win32UsbControllerDevices win32UsbControllerDevices = new Win32UsbControllerDevices();
        private DeviceManagementNotifications deviceManagementNotifications = new DeviceManagementNotifications();



        private void EnableDeviceWatcher(Boolean enable)

控制台示例

static void Main(string[] args)
        {
            UsbDevice[] usbDevices = UsbDevice.GetDevices();

            Console.WriteLine("{0} USB devices:\n", usbDevices.Length);

            foreach (UsbDevice usbDevice in usbDevices)
            {
                Console.WriteLine("VID_{0}&PID_{1}", usbDevice.Vid, usbDevice.Pid);
                Console.WriteLine("Hub:Port = {0}:{1}", usbDevice.Hub, usbDevice.Port);
                Console.WriteLine("Device ID     = {0}", usbDevice.DeviceId);

                foreach (var deviceInterface in usbDevice.Interfaces)
                {
                    Console.WriteLine("Interface ID  = {0}", deviceInterface.InterfaceId);

                Console.WriteLine("LocationInformation = {0}", usbDevice.GetRegistryPropertyValue(UsbDeviceWinApi.DeviceRegistryPropertyKeys.SPDRP_LOCATION_INFORMATION));

                foreach (String locationPath in usbDevice.GetRegistryPropertyValue(UsbDeviceWinApi.DeviceRegistryPropertyKeys.SPDRP_LOCATION_PATHS) as String[])
