	Parent Case:			CROSS REFERENCE TO RELATED APPLICATIONS This application is a continuation-in-part of the co-pending application for “Dual-Personality Extended-USB Plug and Receptacle with PCI-Express or Serial-AT-Attachment Extensions”, U.S. Ser. No. 10/708,172, filed Feb. 12, 2004.
	Family:			Show 17 known family members
	First Claim: Show all 21 claims			1. An extended primary-protocol card comprising: a housing having a primary-protocol form factor for fitting into a host slot for receiving a primary-protocol card; a connector along an insertable edge of the housing, the connector having metal pads for making electrical connection to a primary-protocol host or to an extended-primary-protocol host; wherein the metal pads comprise primary-interface pads and multiplexed pads; wherein the primary-interface pads comprise a primary-protocol-data pad for sending and receiving primary-protocol data; a primary-protocol controller, coupled to the primary-interface pads, for initially communicating with the primary-protocol host by sending primary-protocol data over the primary-protocol-data pad; wherein the multiplexed pads include a first pair of differential data lines for carrying serial data; and an extended-protocol controller, coupled to the multiplexed pads, for serially communicating serial data over the first pair of differential data lines to the extended-primary-protocol host during an extended mode, wherein the primary-protocol data is initially communicated using the primary-interface pads, and serial data is serially communicated over the first pair of differential data lines during the extended mode.
