Yes, but the _underlying_ problem is a communication problem, not an
error in the code. We exaimined your patch, and it doesn't address the
actual problem you are seeing (actually, the existing code in
device.cpp is correct - no channel-id is supposed to be returned if an
I/O error occurs. The fact that device.py may not handle this as
gracefully as it could is another issue.)
So, we need to determine what the real cause is. As Aaron has said, we
have tested extensively with this device (using the most up to date
firmware), and it works OK. So, the question is what else could be
causing this? Could you try using a USB connection?
I was assuming that I would see everything I needed to know in my
console debug logs (-ldebug), but apparently not. I just dug this out
of syslog:

We have located the problem in the code and are working on fixing it. As
you suspected, we are not accessing the proper ports on this device. We
are currently researching the proper port numbers.
Thanks for your patience,
Don
