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: Embodiments disclosed herein include operating the M-PHY communications over peripheral component interconnect (PCI)-based interfaces. Related cables, connectors, systems, and methods are also disclosed. In particular, embodiments disclosed herein take the M-PHY standard compliant signals and direct them through a PCI compliant connector (and optionally cable) so as to allow two M-PHY standard compliant devices having PCI connectors to communicate.
