 *      Added support for practically all devices supported by ActiveSync
 *      on Windows. Thanks to Wes Cilldhaire <billybobjoehenrybob@hotmail.com>.
 *
 * (26/11/2002) ganesh
 *      Added insmod options to specify product and vendor id.
 *      Use modprobe ipaq vendor=0xfoo product=0xbar
 *
 * (26/7/2002) ganesh
 *      Fixed up broken error handling in ipaq_open. Retry the "kickstart"
 *      packet much harder - this drastically reduces connection failures.
 *
 * (30/4/2002) ganesh
 *      Added support for the Casio EM500. Completely untested. Thanks
 *      to info from Nathan <wfilardo@fuse.net>
 *
 * (19/3/2002) ganesh
 *      Don't submit urbs while holding spinlocks. Not strictly necessary
 *      in 2.5.x.
 *
 * (8/3/2002) ganesh
 *      The ipaq sometimes emits a '\0' before the CLIENT string. At this
 *      point of time, the ppp ldisc is not yet attached to the tty, so
 *      n_tty echoes "^ " to the ipaq, which messes up the chat. In 2.5.6-pre2
 *      this causes a panic because echo_char() tries to sleep in interrupt
 *      context.
 *      The fix is to tell the upper layers that this is a raw device so that
 *      echoing is suppressed. Thanks to Lyle Lindholm for a detailed bug
 *      report.
 *
 * (25/2/2002) ganesh
 *      Added support for the HP Jornada 548 and 568. Completely untested.
 *      Thanks to info from Heath Robinson and Arieh Davidoff.
