    Unhappy irw works, but irsend and blaster do not

    I just upgraded and installed a fresh Mythbuntu 14.04 on a system that worked perfectly with Mythbuntu 9 in the past. I have a genuine mceusb receiver with a transmitter attached to it to change channels on a Motorola DCH3200 cable box. I have configured MCC to handle the remotes and transmitter. Following that, I have gone in and edited the correct configuration files for the remote and transmitter in etc/lirc/hardware.conf. I have also ensured that the correct modules and options are defined in /etc/lirc/lircd.conf. The MCE remote works fine within MythTV. However, the IR blasting is not working and consequently I cannot get MythTV to change channels on my STB.

    As part of testing, when I type irw in terminal and click the remote button, I see the proper key presses showing up in terminal. But typing irsend command does not show any errors, nor does it produce any result when I am within MythTV frontend. For example I get:

    $ irsend SEND_ONCE mceusb KEY_UP
    $

    and the focus on the MythTV menu button does not change. (It changes with the remote just fine).

    I have tried irsend SEND_ONCE mceusb -d /dev/lirc KEY_UP, and I get the same result.

    I have also tried irrecord and I can record the key presses successfully into a file.

    Ultimately I want to test out the irsend command with the blaster to get to the channel change part. For example I want to test:

    $irsend SEND_ONCE dch3200 POWER

    to see the bug light up and turn off the power to STB. But it doesn't.

    I know this exact same setup has worked in the past and I wish I could get it up and running again. Any help with troubleshooting will be highly appreciated.

    Perhaps your lircd is actually lircd1

    Try:

    irsend --device=/dev/lircd SEND_ONCE mceusb 1 2 3

    or

    irsend --device=/dev/lircd1 SEND_ONCE mceusb 1 2 3

    Thanks for the suggestion. I will try that and report back.

    Unfortunately neither of those options worked.

    ls -l /dev/lirc*

    shows

    /dev/lirc0
    /dev/lircd -> /run/lirc/lircd

    irsend --device=/dev/lircd SEND_ONCE KEY_UP
    from a terminal goes through without any error, but the focus button in myth doesn't change.

    irsend --device=/dev/lircd1 SEND_ONCE KEY_UP
    gives "irsend : could not connect to socket".

    I had forgot to mention that
    irsend LIST "" ""
    shows both mceusb and DCH3200.

    You need to isolate the error by getting away from the "KEY-UP" command. If you can successfully change to a known channel, you will at least know that irsend is working.

    So, try:

    irsend --device=/dev/lircd SEND_ONCE mceusb 1 2 3

    and go from there.

    Trying to understand the question/situation...
    Mythtv menus respond to your IR remote button presses just fine, but your IRSEND commands do not send out via your IRBLASTER device?

    Problem solved! All I did was change the usb port on the back of the mythtv box where the mceusb transceiver plugged in. And now irsend, ir blaster and channel change script all work.
