  Description:   实现USB驱动Bulk-Only批量传输协议相关函数功能
  Others:        无
  Function List:   
             Bulk_CBWHandler(void)：    接收、处理输出端点(EP2)的传输命令
             
             Bulk_CSWHandler()：          发送执行状态CSW
             
             Bulk_code_transmit(D_UINT8 * pRomData, D_UINT16 len)：  批量发送
             
             IsCBWValid()：     判断是否CBW数据包
             
             Bulk_ErrorHandler(D_UINT8 Status, D_UINT32 wByteCount)：处理状态控制
             
             ChangeEndian(D_UINT8* num)： 转换4字节数据字节序
