Hi all,

I'm using Marverick 10.10 with a Hauppauge HD-PVR on a Zotac ION computer.
Mythtv 0.24.

I followed everything in this thread
http://ubuntuforums.org/showthread.php?t=1598968&page=2 or checked in
various others, still no success in making the IR blaster work.

So I followed Ghosty.be

*you need the zilog.diff patch from 10.04 in your home directory
*you need the new lirc_zilog.c in your home directory from
*you need the binary blob haup-ir-blaster.bin in your home directory from:
http://wilsonet.com/?p=40 (direct link:

and run:
sudo apt-get install lirc-modules-source
cd /usr/src/lirc-*/
sudo patch -p0 < ~/zilog.diff
sudo cp ~/lirc_zilog.c drivers/lirc_zilog
sudo dpkg-reconfigure lirc-modules-source
sudo cp ~/haup-ir-blaster.bin /lib/firmware

sudo rmmod lirc_i2c
sudo rmmod lirc_dev
sudo modprobe lirc_zilog

now you should see as output for: lsmod | grep lirc
lirc_i2c 7433 0
lirc_zilog 15952 0
lirc_dev 12140 2 lirc_i2c,lirc_zilog

and for: ls /dev/lirc*
/dev/lirc0 /dev/lirc1 /dev/lircd

now restart lircd (and make sure it's configured for a hauppage remote)
sudo service lirc restart

But it does not work

First difference
lsmod | grep lirc returns
lirc_zilog 15952 0
lirc_dev 12140 1 lirc_zilog

nothing related lot lirc_i2c, which will appear only if I do sudo modprobe

Second difference and I fear the issue might be coming from here
ls /dev/lirc* returns /dev/lircd only.
no /dev/lirc0 or /dev/lirc1 (which means no device loading no ?)

dmesg |grep lirc
[   13.295756] lirc_dev: IR Remote Control driver registered, major 61
[   13.309819] lirc_zilog: Zilog/Hauppauge IR driver initializing
[   13.316192] lirc_zilog: initialization complete
So apparently no issue on the driver loading.

sudo irsend LIST "" "" returns
irsend: Hauppauge
irsend: hauppauge_pvr
irsend: Hauppauge_350
irsend: Hauppauge_WinTV_Nexus-S
irsend: Hauppauge
irsend: Hauppauge_MVP

The Hauppauge works well, with compiled drivers coming from V4L (linuxtv.org

But it seems nothing is send to the blaster (no blinking light)
irsend SEND_ONCE Hauppauge 0_1_KEY_POWER
irsend SEND_ONCE Hauppauge_MVP 0_1_KEY_POWER
irsend SEND_ONCE hauppauge_pvr 0_1_KEY_POWER
returns #unknown command"

sudo irsend SEND_ONCE hauppauge_pvr POWER returns nothing.

Any idea of what might be wrong ?
