My reasoning for suggesting a launchd plist for the driver is
that launchd can respawn the driver if necessary - which would
be helpful in your case if the device disconnects. (However, I
seem to remember that you said the driver still reports "data
stale", which means it has not treated the error code as a
"device disconnection". We need to work on that.)
I don't believe I've had a 'data stale' error when running
driver in debug mode. Or maybe I'm not following what you're saying.
But I have now... after running for around 8 hours in debug
mode; I'm now getting "Data stale" errors via upsmon:
14/03/10 4:26:06 AM upsmon[15330] Communications with UPS
powerware5...@localhost established

[powerware5...@localhost] failed - Data stale
14/03/10 12:29:28 PM upsmon[15330] Poll UPS
[powerware5...@localhost] failed - Data stale
And I'm not able to quit the driver now:
$ sudo killall -9 bcmxcp_usb
$ ps ax | grep bcmxcp
15641 ?? Us 0:22.34 /usr/local/ups/bin/bcmxcp_usb -D -a powerware5115
I can't unload that job via launchctl either. And since I was
sending all the debug output to /dev/null, I don't have any
clues from there. I'll test again without redirecting stderr (if
I can figure out how to kill the driver). Can you suggest any
way to kill the driver short of a restart?
And I answered my own question (leaving it here in case it helps
someone else later). I re/plugged the UPS USB cable and the
driver died. When/if I get the 'data stale' error again I'll
send anything from the debug log that looks relevant.
Thanks,
Charlie
