Abstract
An integrated circuit for a smart card in accordance with an exemplary embodiment includes at least one data terminal for providing communications with a host device over a system bus and a processor configured to provide an attachment signal on the at least one data terminal for recognition by the host device. Further, the processor also cooperates with the host device to perform an enumeration based upon at least one default descriptor, and receive information from the host device regarding a system event. In addition, the processor is configured to remove the attachment signal from the at least one data terminal and thereafter again provide the attachment signal on the at least one data terminal based upon the information regarding the system event, and cooperate with the host device to perform a new enumeration based upon at least one alternate descriptor.
