USB模拟U盘实验中[mw_shl_code=cpp,true]        /* Enable the USB interrupt */
        NVIC_InitStructure.NVIC_IRQChannel = USB_LP_CAN1_RX0_IRQn;        //组2，优先级次之
        NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 1;
        NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
        NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
        NVIC_Init(&NVIC_InitStructure);
       
        /* Enable the USB Wake-up interrupt */
        NVIC_InitStructure.NVIC_IRQChannel = USBWakeUp_IRQn;   //组2，优先级最高
        NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
        NVIC_Init(&NVIC_InitStructure); [/mw_shl_code]
USB的中断抢占优先级是1，次优先级是0 ，这个优先级再加入其他优先级后，SD 卡的SPI2的优先级是否也被包含在USB 的优先级中断中？
