Hey all, thanks for your work on nut. I recently got myself a new cheap UPS, and have thus far determined very little about it. I can run whatever you like to help identify and work with it. So far I've played around with various settings and have had some limited success with the megatec_usb driver (Debian testing version):
----ups.conf---- [plexus] driver=megatec_usb model=500VA mfr=Plexus vendorid=0001 #port=auto port=/dev/usb/hiddev0 desc="Plexus V 500VA UPS" ----ups.conf----
$:/lib/nut# ./megatec_usb -a plexus Network UPS Tools 2.2.1- - Megatec protocol driver 1.5.9 [megatec_usb] Carlos Rodrigues (c) 2003-2007 Serial-over-USB transport layer for Megatec protocol driver [megatec_usb] Andrey Lelikov (c) 2006, Alexander Gordeev (c) 2006-2007, Jon Gough (c) 2007 Megatec protocol UPS detected [ UPS500V VER3.10C]. This UPS has an unsupported combination of battery voltage/number of batteries. Cannot calculate charge percentage for this UPS.
...and some debugging output:

Looking at similar mails in the archives I guess you need some of those values for the battery table in the driver, but I'm not clear which. - Jamie
