IEC 62680-2-1 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.

 IEC 62680-2-1 定义了行业标准 USB。 该规范描述了设计和构建符合该标准的系统和外设所需的总线属性、协议定义、事务类型、总线管理以及编程接口。 目标是使来自不同供应商的此类设备能够在开放架构中互操作。 该规范旨在增强 PC 架构，涵盖便携式、商用台式机和家庭环境。 该规范旨在为系统 OEM 和外围设备开发商提供足够的产品多功能性和市场差异化空间，而无需承担过时接口或失去兼容性的负担。
