Discovery mechanisms for universal serial bus (USB) protocol adaptation layer

摘要

A WiFi serial bus (WSB) attribute for use in Wi-Fi Alliance defined point-to-point (P2P) discovery mechanism includes a plurality of fields disposed in the frame. The WiFi serial bus attribute is arranged to provide information in the plurality of fields to support connectivity decisions for a USB device in a point-to-point network using a WSB protocol. The WSB attribute includes WSB architectural element information and information associated with a USB device behind a USB protocol adaptation layer (PAL).

主权项

1. A data structure embodied on a non-transient computer-readable storage medium, comprising:
a packet header to provide identification of a destination of a frame; and a WiFi serial bus (WSB) attribute comprising a plurality of fields disposed in the frame, the WSB attribute arranged to provide information in the plurality of fields to support connectivity decisions for a universal serial bus (USB) device in a point-to-point network using a WSB protocol, wherein the WSB protocol includes support for a USB protocol adaptation layer (PAL) to support USB traffic over WiFi links, wherein the WSB attribute includes WSB architectural element information and information associated with a USB device behind a USB protocol adaptation layer (PAL), and wherein the WSB architectural element information includes a WSB support field to indicate a support of the WSB protocol, a WSB version field to identify a version of the WSB protocol supported by the USB device, a WSB role field to identify a role for the USB device, an IP-support field identifying whether the USB device supports USB PAL over IP; a WSB string field to provide a user friendly description of the USB device, and a WSB icon filed to provide a depiction of an icon for the USB device.
