In a preferred embodiment, the computer peripheral is equipped with one or more hardware interfaces. The interface connector cable has a first end connector for attaching to the computer peripheral. The first end connector of the interface connector cable is typically a multiple pin connector constructed and arranged to be properly physically and electrically connectable only to a specific computer peripheral or class of computer peripherals, the first end connector including at least one electrical connection between two pins for completing a circuit within the computer peripheral thereby enabling the computer peripheral. Where the peripheral is a data reading device such as a laser scanner or RFID reader, alternate or additional configuration may be obtained, with data reading device, from the label on the interconnect cable. The label, which may for example be a bar code or RFID tag, contains information or instructions by which the data reading device (and/or the host) is configured. ## Claims ### Claim 1 A method for interfacing a data reader of a data reading system with a particular host, comprising the steps of identifying the data reader;
