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

Abstract

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).
