USB海量存储设备类规范包括四个独立的子类规范:(ATA command的那个没有) ①USB Mass Storgage Class Control/Bulk/Interrupt(CBI)Transport ②USB Mass Storage Class Bulk-Only Transport ③USB Mass Storage Class ATA Command Block ④USB Mass Stroage Class UFI Command Specification。 前两个子规范定义了数据/命令/状态在USB上的传输方法。 Bulk-Only传输规范仅仅使用Bulk端点传送数据/命令/状态, CBI传输规范则使用Control/Bulk/Interrupt三种类型的端点进行数据/命令/状态传送。 后两个子规范定义了对存储介质的操作命令。 ATA 命令规范用于硬盘。 UFI命令规范是针对USB移动存储而制定的,实际上UFI命令格式是基于SFF-8070i和SCSI-2规范,总共定义了19个12字节长度的操作命令。
