I made a previous post about this in Installation, but I meant to post it here as it seems more of a hardware issue. Anyway, I went back to my old post but it wont let me delete it, so I'm sorry for the double-post.

I really hope someone can help me with these issues.
I have been pulling my hair out trying to get a Hauppauge PVR-150 MCE version to change channels on a Motorola DCT2224 Cable Box.
I have the remote working OK, but the IRBlaster is a USB type interface that came with the Hauppauge PVR-150MCE.
Is it possible to get the USB IRBlaster from this to work in KnoppMyth?
I have been scouring forums looking for answers, but all I ever see are posts about getting a regular PVR-150 IR Blaster to work, but none for the USB version of the IRBlaster.
If it can be made to work, exactly what steps should I take to make it work?

Any help on this issue would be GREATLY appreciated.
Thanks in advance.

I have been trying to make this work for some time now, still no luck. If anybody out there has some suggestions, any help would be greatly appreciated.

To reiterate, I am trying to make a Hauppauge PVR-150MCE's USB IR Blaster work with a Motorola DCT-2224 Cable Box.

Originally, I ran through MythTV main setup and selected that I did not have a Serial IR Blaster (because it's a USB IR Blaster that comes with the MCE version of a Hauppauge PVR-150, not a serial blaster). I'm guessing that I selected that wrong however because the IR Blaster did not work.
After that, I ran the master setup again with the following command.
"touch /home/mythtv/.configure" then rebooted.

This time I told it I had a serial IR blaster, but it asked me if I was connected to serial port 1 or 2.....since I'm using a USB IR Blaster it's neither....but USB was not an option so I selected serial 1.

I then reconfigured all my backend stuff and everything worked like it did before....almost.....this time it changes the channel on my PVR-150 tuner instead of keeping it on channel 4 like it used to......I checked my config several times and it is being told that I am connected to a STB and that the channel needs to stay on 4 for the tuner card.....but for some reason it still tries to change channels on it......Also, the IR Blaster still does not work.

If MythTV WILL use a USB version of the PVR-150 IR Blaster, do I tell Myth Setup that I have a serial IR Blaster or do I tell it nothing.....it does not ask about a USB IR Blaster, only a serial IR.
The remote I'm using worked right out of the bow. It was a remote that came with the CPU Case that I'm using for MythTV. It had a built in remote receiver. All I had to do was change the keybinds in Myth to those put out by the remote, which it reads as a simple keyboard.
But the USB IR Blaster will not work on the STB no matter how I change it in setup.

I have searched all over the place for over a week now and I am no closer to figuring out how to make this work.....I'm not even sure a USB Ir Blaster WILL work in MythTV.
I'm guessing at this point that I have to do something with LIRC, but I am still new to MythTV and to Linux and I have no idea what to do.
I found a file on the LIRC web site for a DCT-2224 STB which I presume I need to do something with, but I am completely lost as to what I need to do with it.

Could somebody please point me in the right direction?
Thanks in advance.

Here is a file I got from the LIRC site for the DCT2224 STB....but I don't know what to do with it.

Using some info from here..............
http://www.eggshellskull.com/lirc/blast ... .php#step4

I am able to presume the following.
1. I need to append the DCT2224 file from above into "/etc/lircd.conf"
2. I need to create a file called "/cc.sh" and paste the following into it.
Code:
#!/bin/bash
REMOTE_NAME=Motorola_DCT2224
for digit in $(echo $1 | sed -e 's/./& /g'); do
irsend --device=/dev/lircd1 SEND_ONCE $REMOTE_NAME $digit
sleep 0.4 # note, you may have to tweak the interdigit delay up a bit
done
irsend --device=/dev/lircd1 SEND_ONCE $REMOTE_NAME OK

3. Run mythtv-setup and tell input "device" to use the "/cc.sh" script to change channels.

Am I close?
All the info I can find on this topic is about a serial IR Blaster though.....I have never found anything regarding a USB IR Blaster.
Will this work for a USB IR Blaster?

Anybody who has gotten this setup with a USB IR Blaster please gimme some info.
Thanks

MojoJOJO :)

I've been reading this, sorry I've not piped in as I have nothing to pipe in with (and I've been busy w/ R6)... I'll take a look at the link and see what it states.

Thanks for the help....greatly appreciated. I am going to give this info a try asap, but all the info above is for a serial IR blaster and I have googled until my eyes bled and have yet to find any info for a USB IR blaster.
I don't know what I should choose in MythTV master setup for IR blaster because it asks if I have a "Serial" IR blaster, which clearly I do not, but does that mean it will assume that I don't have an IR blaster at all?

Again though, thanks for the help....it is very much appreciated.
Hope to get this issue sorted out soon.

A few things come to mind... grep dmesg for the device. Do you see it? Perhaps something like /dev/input/X? Try changing the script to use that instead of a regular serial port.

mojoJOJO, what version of Lirc do have running? I ran into a problem with a MS remote and USB receiver I got from Pinnacle. The USB receiver uses a new vendor model that lirc 8.3 does not know about, but it is 8.4. Or you can add the missing 3 lines to the 8.3 source code and recompile it.

Thanks for the reply.
I'm not sure what version I have. I am running KnoppMyth r5.5 so whatever version comes with that....I believe its lirc 0.8.3 but I'm not sure.
How would I check that, and once checked, how would I go about either updating or recompiling? Sorry for the barrage of questions, but I'm still not used to linux just yet.
