>>> Lets first explain what is what and created by what:
>>> 1: When the kernel loads the support for lirc it creates through udev
>>>    the devices /dev/lirc0 and /dev/lirc1 and through your own rule
>>>    udev adds the simlink /dev/lircSerial. Without the card the last
>>>    will point to /dev/lirc0 and with the card to /dev/lirc1.
>>> 2: Then comes in lircd (remember the extra d) lirc will create a
>>>    socket (which is a kind of doorway) to the desired device.
>>>    /var/run/lircd and a link to this socket in /dev/ /dev/lircd.
>>>    You originally configured it through mcc and this program probably
>>>    creates the file /etc/lirc/hardware.conf.
>>>    By default this socket is called lircd. To prevent the new card
>>>    from interfering we tried to give the socketfile it own uniek name.
>>>
>>> This all seemed to work but have you tried if it worked with irsend -d
