A cable, connector and keying system that support conventional Universal Serial Bus (USB) signals on a first end and a second connector associated with the cable and system is operative in at least two mechanical positions. Based upon the selected mechanical position, the cable is configured to allow certain functions and/or prohibit certain functions. For example, when the connector is in a first position, it may be desirable to connect an accessory device to the mobile telephone through the cable. However, when the connector is in a second position, it may be desirable to prevent the user from connecting the accessory device to the mobile telephone because, for example, when the cable is operating in the configured mode damage may occur to the accessory device.
