hi,

i've bought a 750VA orvaldi ups http://en.orvaldi.com/index.php/en/product_catalog/product_view/11/162
which holds my hardware (wifi router, cable modem, quad-core with raid and lcd monitor) for ~15 minutes.
pretty nice result for a cheap (~57 euro) home ups.

in fact, the vendor software for linux is very old (e.g. requires ancient redhat with qt2),
requires db9 port while shipped product has serial-over-usb converter,
so the nut package is my only hope in this area.

afaics in other orvaldi's data sheets they use megatec protocol, so i've tested followinf scenario:

1). connect usb cable to ups.

/* on fresh 2.6.36 kernel from git */

2). add [orvaldi] entry to /etc/ups/ups.conf:

[orvaldi]
        driver = megatec_usb
        port = /dev/input/by-id/usb-0665_WayTech_USB-RS232_Interface__V1.0__Baud_rate_2400bps-event-if00
                                 ^^^^ this is a udev-maintained symlink to proper /dev/input/eventX.
        desc = "Orvaldi"

3). test the driver:

# /lib/nut/upsdrvctl -u root -D start orvaldi
Network UPS Tools - UPS driver controller 2.4.3
   0.000000     Starting UPS: orvaldi

in dmesg i see only:

from the other side, there's a working windows software installed on my laptop.
i can sniff it with your help to provide required info for further nut development.

BR,
Pawel.
