Thanks for the suggestion. Is the following useful information?

$ sudo /usr/local/ups/sbin/upsd -DDD

And I've found more info while testing which hopefully is a 
clue. If I start the driver with either of these commands:

$ sudo /usr/local/ups/bin/upsdrvctl start
$ sudo /usr/local/ups/bin/bcmxcp_usb -a powerware5115

Then I get the 'data stale' error. But if I start the driver with:

$ sudo /usr/local/ups/bin/bcmxcp_usb -D -a powerware5115

Then I can run upsc and get an answer. So it works when running 
with driver in debug mode.
