Abstract: In a Universal Serial Bus (USB) enumeration procedure, a USB Host questions a USB Device for its capabilities and chooses a set of capabilities that best fit. When the USB Device is enumerated, the USB Host may perform several time-consuming and power-consuming operations. However, when the USB Device is tightly or permanently coupled to the USB Host, part of the enumeration procedure may be redundant and can be eliminated. Accordingly, a method, an apparatus, and a computer program product for shortening enumeration of the USB Device tightly coupled to the USB Host are provided. The USB Host sends a request for a Device descriptor to the USB Device, receives a plurality of descriptors in a single transfer from the USB Device, and sets a configuration of the USB Device based on the received plurality of descriptors.

Abstract translation: 在通用串行总线（USB）枚举程序中，USB主机向USB设备询问其功能，并选择最适合的一组功能。 枚举USB设备时，USB主机可能会执行多次耗时且耗电的操作。 然而，当USB设备紧密或永久地耦合到USB主机时，枚举过程的一部分可能是冗余的并且可以被消除。 因此，提供了一种用于缩短与USB主机紧密耦合的USB设备的枚举的方法，设备和计算机程序产品。 USB主机向USB设备发送针对设备描述符的请求，从USB设备接收单个传送中的多个描述符，并且基于所接收的多个描述符来设置USB设备的配置。
