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@xxxxxxxxxxxxxxx (which will likely end up in my inbox anyway
eventually).
thanks, Lars

This adds support for the Pulse-Eight USB CEC dongle. It has been tested
with both v4 and v5 firmware.
It is still in staging because 1) the CEC framework it depends on is still in
staging, 2) the code needs to be refactored a bit and 3) it needs more testing.
That said, it's in pretty decent shape. It's pretty neat, but I do wish it
would support a CEC bus snooping mode: that would make it an ideal CEC bus
sniffer. But I don't see any support for it, unfortunately.
If anyone knows how this can be achieved then please let me know!
Please note that this needs support from inputattach (part of linuxconsoletools),
a patch is included in the TODO file.
Regards,
Hans
