Re: [PATCH 0/5] Pulse-Eight USB CEC driver

[Lars Op den Kamp <lars@opdenkamp.eu>]

Hi Hans,

I'm subscribed to this mailing list, though haven't been participating 
in discussions here (no time). I work for Pulse-Eight and did most of 
the CEC software.

There's no difference between firmware v4 and v5 for the USB model of 
the adapter. v5 just adds support for the new Intel NUC internal CEC 
adapter.

You can snoop the bus by setting the ack mask to 0 and just read what 
comes in (MSGCODE_SET_ACK_MASK 0)
This is the same as "cec-client -m" does when using libCEC: 
https://github.com/Pulse-Eight/libcec/blob/master/src/libcec/adapter/Pulse-Eight/USBCECAdapterCommands.cpp#L584

Let me know if you need more help, or send an email to 
support@pulse-eight.com (which will likely end up in my inbox anyway 
eventually).

thanks, Lars
