        The USB slave serial package supports the development of USB
        peripherals which mimic a serial connection to the host
        machine. Such a device creates a relatively simple upgrade to
        USB from a legacy serial connection, especially from the
        perspective of the host software and device drivers."

            endpoints, while the ACM device also requires an Interrupt
            IN endpoint.  For a Windows host, the ACM configuration is
            required to use the standard 'usbser.sys' device driver,
