请教STM32 USB 组合设备(composite device)的问题。

想用STM32 USB实现MASS STORAGE与 VIRTUAL COM，请教下面的这个初始化函数如何合并才能同时对两个应用初始化呢？
DEVICE_PROP Device_Property =
  {
MASS_init,
MASS_Reset,
MASS_Status_In,
MASS_Status_Out,
MASS_Data_Setup,
MASS_NoData_Setup,
MASS_Get_Interface_Setting,
MASS_GetDeviceDescriptor,
MASS_GetConfigDescriptor,
MASS_GetStringDescriptor,
0,
0x40;
}

这是VIRTUAL COM 的：
DEVICE_PROP Device_Property =
  {
Virtual_Com_Port_init,
Virtual_Com_Port_Reset,
Virtual_Com_Port_Status_In,
Virtual_Com_Port_Status_Out,
Virtual_Com_Port_Data_Setup,
Virtual_Com_Port_NoData_Setup,
Virtual_Com_Port_Get_Interface_Setting,
Virtual_Com_Port_GetDeviceDescriptor,
Virtual_Com_Port_GetConfigDescriptor,
Virtual_Com_Port_GetStringDescriptor,
0,
0x40 /*MAX PACKET SIZE*/
  };
请大家指教，谢谢了！
