Hi,

I was able to use megatec_usb with a Powermust 1000VA USB with the hal
driver activated (hald-addon-megatec_usb). If you are lucky, megatec_usb
will be able to recognize your ups if you force the "agiler" subdriver
in your ups.conf.

Here is my config:

 sys-power/nut-2.2.0 with both hal and usb supports,

ups.conf  (productid/vendorid will probably differ 06da,0003?),

 [PowerMust]
       driver = megatec_usb
       port=auto
       vendorid = 0665
       productid = 5161
       subdriver = "agiler"
       desc = "Mustek PowerMust 1000Va USB"
       mfr = "Mustek"
       model = "PowerMust 1000 USB"


Also, hald fills up dmesg with a lot of "uninitialized something"
messages related to the hald-addon-xxx driver. It was quite annoying.
That's why i don't use it anymore (gnome-power-manager will recognize
your nut device through hald).

Also, I changed 52_nut-usbups.rules with 52-nut-usbups.rules in 
Makefile.in to help udev to understand it  (sed -e
"s:52_nut-usbups.rules:52-nut-usbups.rules:" -i
scripts/udev/Makefile.in) - probably unnecessary now.
