The above log looks good to me. There is just the unexpected run
state, but that's not fatal, just a warning. The check for those
bits is an arbitrary choice anyway, could not tell how certain
that expectation even is, or whether the first supported devices
just happened to always come up with this bit pattern, while none
of it is essential. Check the git history if you are interested
in the evolution of that driver and the set of supported devices.
The above log stops after the detection, does not include the
start of an acquisition. The other log in the other message says
"no device" when trying to configure an acquisition. Which could
have a different cause than speaking the wrong protocol (like
cable/connection issue, device unplugged, power outage, etc). So
that needs verification (re-execution after cable and port
checks, checks for power drops, etc).
