window 如何枚举设备并禁用该设备和启用该设备？如何注册设备热拔插消息通知？

目前实现的功能：
1.设备枚举
2.设置设备禁用和启用
3.注册设备热拔插消息通知
4.获取设备 vid pid 数值

需要链接的库 SetupAPI.lib

	// Routine Description:
	//     Registers an HWND for notification of changes in the device interfaces
	//     for the specified interface class GUID. 

	// Parameters:
	//     InterfaceClassGuid - The interface class GUID for the device 
	//         interfaces. 

	//     hWnd - Window handle to receive notifications.

	//     hDeviceNotify - Receives the device notification handle. On failure, 
	//         this value is NULL.

	// Return Value:
	//     If the function succeeds, the return value is TRUE.
	//     If the function fails, the return value is FALSE.

	// Note:
	//     RegisterDeviceNotification also allows a service handle be used,
	//     so a similar wrapper function to this one supporting that scenario
	//     could be made from this template.
