1、初始化设备热插拔消息，注册回调函数
代码如下：

#include <fltKernel.h>
#include <wdmguid.h>

DEFINE_GUID(GUID_DEVINTERFACE_USB_DEVICE,
	0xA5DCBF10, 0x6530, 0x11D2, 0x90, 0x1F, 0x00, 0xC0, 0x4F, 0xB9, 0x51, 0xED);

PVOID g_notificationEntry = NULL;

//回调函数
NTSTATUS NotificationCallback(IN PVOID NotificationStructure,IN PVOID Context);

//初始化设备热插拔消息
NTSTATUS HotPlugInit(_In_ PDRIVER_OBJECT DriverObject)
{
   
	NTSTATUS status = STATUS_SUCCESS;
	//初始化设备热插拔消息，注册回调函数
	status = IoRegisterPlugPlayNotification(
		EventCategoryDeviceInterfaceChange,
		PNPNOTIFY_DEVICE_INTERFACE_INCLUDE_EXISTING_INTERFACES,
		&GUID_DEVINTERFACE_USB_DEVICE,
		DriverObject,
		NotificationCallback,
		NULL, &g_notificationEntry
	);

	//判断是否注册成功
	if (!NT_SUCCESS(status))
	{
   
		KdPrint(
