this is the communication socket between the driver and upsd (the server).

first, can you try with blazer_usb, since it's set to replace megatec.
Next, after having stopped NUT, launch the following (as root):
$ /path/to/blazer_usb -DDD -a  powerwalker

let it run for ~30 seconds, and send us back the output.
also send us your ups.conf, along with the output of "lsusb"

cheers,
Arnaud
