    For another alternative, try:

            http://www.gank.org/freebsd/cdce.tar.gz

    Unpack it anywhere, then cd to that directory (as root) and:

            make
            make install
            kldload if_cdce

    Then plug in the cable from your Zarus - you should wind up with
    a cdce0 device that you'll need to ifconfig. (You can add an entry
    to usbd.conf to do that automatically.)

    I downloaded a copy to use with my YOPY. (I needed to add a config
    line and the #define statements; but that's all it took. For anyone
    trying this with their own YOPY, leave off the CDCE_ZAURUS flag from
    the YOPY config line.)

    Now that that's out of the way, Sangwoo, could you post the details
    of your dubp + ng_eiface solution? I might want to switch to that.
