this should be due to the call of "HIDIOCINITREPORT" before getting
each report (== data).
This was needed for some APC models, but seems to cause problems
to others... Does your driver continue to update data?

Anyway, your best bet is to try newhidups, as this one will soon replace
the old linux only hidups.

But there are point missing (not sure, as it seems the shutoff (== ups
poweroff) is not supported for APC in hidups), that are under investigation
by APC users... If you want to join, you're welcome.
