Use external CEC adapter

  • Hello,

    I have some problem with Amlogic CEC device so I add an external CEC device (Puse Eight).

    The problem is that I can not use it:

    I disable the built in CEC, is the second device port well? It will be somethig like this "/dev/ttyACM1".

    I can not switch off the TV with this command:

    How could I use the external CEC? I am missing something?

    Regards.
