Here's the culprit:

   5.338858	status interrupt read: error sending control message: Operation not permitted

What does 'ls -l /dev/bus/usb/005/002' say? If the UPS has been unplugged since the logs were generated, replace "005/002" with the path suffix from this set of messages:

   5.499162	Checking USB device [0001:0000] (005/002)
   5.510156	- VendorID     : 0001
   5.510202	- ProductID    : 0000
   5.510209	- Manufacturer : ATCL FOR UPS
   5.510219	- Product      : ATCL FOR UPS
   5.510225	- Serial Number: ATCL FOR UPS
   5.510231	- Bus          : 005
   5.510237	Matched expected vendor='ATCL FOR UPS'.
   5.512216	USB device [0001:0000] opened

Depending on your distribution and how you installed NUT, some extra steps may be necessary to fix the permissions every time the UPS is plugged in. (NUT ships with a udev rules file.)

We need to fix the logging levels - the permissions message should have been logged at a higher priority.
