IEC 62680-2-1:2015（E）定义了行业标准USB。本规范描述了设计和构建符合本标准的系统和外围设备所需的总线属性、协议定义、事务类型、总线管理和编程接口。其目标是使来自不同供应商的此类设备能够在开放式体系结构中进行互操作。该规范旨在增强PC体系结构，涵盖便携式、商务桌面和家庭环境。该规范旨在允许系统原始设备制造商和外围设备开发人员有足够的空间实现产品的多功能性和市场差异化，而不会带来过时的接口或失去兼容性的负担。

IEC 62680-2-1:2015(E) defines an industry-standard USB. The specification describes the bus attributes, the protocol definition, types of transactions, bus management, and the programming interface required to design and build systems and peripherals that are compliant with this standard. The goal is to enable such devices from different vendors to interoperate in an open architecture. The specification is intended as an enhancement to the PC architecture, spanning portable, business desktop, and home environments. It is intended that the specification allow system OEMs and peripheral developers adequate room for product versatility and market differentiation without the burden of carrying obsolete interfaces or losing compatibility.
