手把手教你使用USB的CDC+MSC复合设备（基于stm32f407）- 2

接上文：手把手教你使用USB的CDC+MSC复合设备（基于stm32f407）

此文主要是记录一下usb枚举时抓取的一些数据以及usb msc涉及的部分scsi协议。

USB MSC协议

主要包括usb协议、msc类协议、scsi协议、SDIO接口协议，流程图如下，描述了Host与Dev之间通信的过程。
在这里插入图片描述

SCSI协议

SCSI：Small Computer System Interface，小型计算机系统接口的缩写，说人话就是Host通过usb协议与设备进行通信，usb协议内的数据又使用 SCSI协议来传输sd卡或硬盘数据，来达到电脑上挂载SD卡并读写文件的功能。
常用的几个SCSI协议如下：

命令码	描述	含义
0x00	SCSI_TEST_UNIT_READY	测试命令，经常使用
0x12	SCSI_INQUIRY	查询基本信息命令，包括厂商、版本等信息
0x1a	SCSI_MODE_SENSE6	模式检测，提供一系列设备服务、报告参数等
0x15	SCSI_MODE_SELECT6	模式选择，与上0x1a对应
0x23	SCSI_READ_FORMAT_CAPACITIES	读取可支持的格式化容量
0x25	SCSI_READ_CAPACITY10	读取当前SD卡容量
0x28	SCSI_READ10	读数据命令
0x2f	SCSI_WRITE10	写数据容量
…	…	…
