1. An integrated circuit for a smart card and comprising: at least one data terminal for providing communications with a host device; and a processor for providing an attachment signal on the at least one data terminal for recognition by the host device, cooperating with the host device to perform an enumeration based upon at least one default descriptor, and based upon a system event, selectively removing the attachment signal from the at least one data terminal and thereafter again providing the attachment signal on said at least one data terminal and cooperating with the host device to perform a new enumeration based upon at least one alternate descriptor.
