USB移动存储设备的检测、写入及弹出

USB设备的基本操作涉及USB存储设备的插入检测及写入文件，同时可以在写入结束后自动弹出，下面介绍自己的实现方法。

（1）注册设备。

在检测之前需要对检测的设备进行注册。具体的代码如下：

//首先注册设备
void CUSBTestDlg::OnBtnRegister()
{
 // TODO: Add your control notification handler code here

 static const GUID GUID_DEVINTERFACE_LSIT[] =
 {
 //GUID_DEVINTERFACE_USB_DEVICE
 {0xA5DCBF10,0x6530,0x11D2,{0x90,0x1F,0x00,0xC0,0x4F,0xB9,0x51,0xED}},
 //GUID_DEVINTERFACE_DISK
 {0X53F56307,0XB6BF,0X11D0,{0X94,0XF2,0X00,0XA0,0XC9,0X1E,0XFB,0X8B}},
 //GUID_DEVINTERFACE_HID
 {0X4D1E55B2,0XF16F,0X11CF,{0X88,0XCB,0X00,0X11,0X11,0X00,0X00,0X30}},
 //GUID_NDIS_LAN_CLASS
 {0XAD498944,0X762F,0X11D0,{0X8D,0XCB,0X00,0X00,0X4F,0XC3,0X35,0X8C}}
 };
 //注册插拔事件
 HDEVNOTIFY hDevNotify;
 DEV_BROADCAST_DEVICEINTERFACE NotifacationFiler;
 ZeroMemory(&NotifacationFiler,sizeof(DEV_BROADCAST_DEVICEINTERFACE));
 NotifacationFiler.dbcc_size = sizeof(DEV_BROADCAST_DEVICEINTERFACE);
 NotifacationFiler.dbcc_devicetype = DBT_DEVTYP_DEVICEINTERFACE;
 
 for(int i=0;i<sizeof(GUID_DEVINTERFACE_LSIT)/sizeof(GUID);i++)
 {
  NotifacationFiler.dbcc_classguid = GUID_DEVINTERFACE_LSIT[i];//GetCurrentUSBGUID();//m_usb->GetDriverGUID();

  hDevNotify = RegisterDeviceNotification(m_hWnd,&NotifacationFil
