[Nut-upsuser] Problems with newhidups and Smart-UPS 750

[Peter Selinger]

Strange. Is the problem reproducible? I have never seen it before. 

You might try the Development version of NUT from SVN (see
http://www.networkupstools.org/source.html under "Development tree").
There has been quite a lot of work on the newhidups driver since
2.0.4.
