Nut upsuser - Dec 2007 - Plexus UPS 1000V - megatec_usb

Hi,

Just purchashed this UPS.

The megatec_usb driver appears to be communicating with the UPS - 
however, the ups.status field always states "off"

There was a report about the same thing.
http://lists.alioth.debian.org/pipermail/nut-upsdev/2007-September/002526.html

IMO the problem should be solved on the megatec protocol level ie in the
megatec driver. It is not related to what megatec_usb does - emulating a
serial interface over USB connection. Is this ok?
