         {
            HANDLE hDrive = CreateFile( pspdidd-&gt;DevicePath,0,
                                        FILE_SHARE_READ | FILE_SHARE_WRITE,

            {

               if ( usbDeviceNumber == volumeDeviceNumber ) 
               {
                  fprintf( "%s", pspdidd-&gt;DevicePath );
               }

         }
      }
      dwIndex++;
   } 
   SetupDiDestroyDeviceInfoList(hDevInfo);
   return;  
}

您可以通过使用设备的句柄：呼叫DeviceIOControl()来获得设备编号

DWORD getDeviceNumber( HANDLE deviceHandle )
{
   STORAGE_DEVICE_NUMBER sdn;
   sdn.DeviceNumber = -1;
   DWORD dwBytesReturned = 0;
   if ( !DeviceIoControl( deviceHandle,
                          IOCTL_STORAGE_GET_DEVICE_NUMBER,
                          NULL, 0, &sdn, sizeof( sdn ),
                          &dwBytesReturned, NULL ) )
   {
      // handle error - like a bad handle.
      return U32_MAX;
   }
   return sdn.DeviceNumber;
}

接下来是一种识别卷是否是可移动介质的方法（例如，像usb或firewire磁盘）：

bool isRemovableMedia( s32 vol )
{
   char rootPath[5] = "@:\";
   rootPath[0] = (char)( vol + 'A' );
   char szDosDeviceName[MAX_PATH];
   char dosDevicePath[3] = "@:";
   // get the drive type
   UINT DriveType = GetDriveType( rootPath );
   if ( DriveType != DRIVE_REMOVABLE )
      return false;
   dosDevicePath[0] = (char)( vol + 'A' );
   QueryDosDevice( dosDevicePath, szDosDeviceName, MAX_PATH );
   if ( strstr( szDosDeviceName,"\Floppy") != NULL )
   {
      // its a floppy
      return false;
   }
   return true;
}
