your first issue, above, is a privilege one.
that is, the nut configured user has not enough rights to access the device
in RW mode.
this is addressed on Linux through udev, and the helper files found in
scripts/udev, in the source tree.
just copy scripts/udev/52-nut-usbups.rules to /lib/udev/rules.d, and call
$ udevadm trigger --subsystem-match=usb --action=change

then unplug/replug your UPS USB cord, and everything should be fixed.

nothing wrong there, it's just that the device has no change to report by
itself, between the polling requests from the driver...

cheers,
