    I installed v21 according to these instructions:
    sudo apt-get install update
    sudo apt-get upgrade
    sudo apt-get install libusb-1.0-0-dev

    Install mochad:
    (assuming mochad-0.1.21.tgz is in /home/pi/ )
    tar xf /home/pi/mochad-0.1.21.tgz

    cd /home/pi/mochad-0.1.21
    ./configure
    make
    sudo make install

    Connect the CM15Pro with your Rasp with the USB interface.

    Command line to test:
    $ echo "pl a1 on" | nc -w 1 localhost 1099

    with no errors on installation, then plugged in my CM19. The test line given returned nothing, and mochad -d gave me an error that libusb couldn't open the device. What now?

    Thanks for any help.

    I should add that I tried the mochad-master patch from 2016 and that didn't help. running sudo mochad -d will start it manually, but I don't think that's a fix.

    Timothy, try sending "rf" command instead of "pl". CM15 has both Power Line and RF interfaces but CM19 has only the RF.
    So, try the command:
    $ echo "rf a1 on" | nc -w 1 localhost 1099

    Rodrigo, thanks. I switched to using heyu to control my X10 devices, and that works well.
