(leaving the full bug report for the NUT team)

I vaguely remember something with this driver and the default subdriver
used.
Alex may have more info.

can you check the latest development version (subversion trunk).
For more info on getting and compiling the development release:
http://buildbot.ghz.cc/~buildbot/docs/r2003-144/website/download.html

Note that you don't need to install nut ; simply running from the build
directory is sufficient, using:
$ sudo ./drivers/megatec_usb -DDDDD -a <upsname>

you might also give a try to blazer_usb, which will replace megatec*
$ sudo /lib/nut/blazer_usb -DDDDD -a <upsname>
and/or
$ sudo ./drivers/blazer_usb -DDDDD -a <upsname>

cheers,
Arnaud

megatec_usb from trunk still fails.
blazer_usb from trunk does work, but not blazer_usb from 2.4.1-2ubuntu4.

Bjorn,

I was wondering if you could try the karmic version.

Thanks

I extracted the megatec_usb and blazer_usb from the 2.4.1-3ubuntu2 and tried them using the method in comment 5. No sucess though.

thanks for these tests and feedback.
reading back the thread, blazer_usb in the trunk is working.
the fact is that there were changes here, but no version bump (still
0.03) which led to confusion here.

the attached patch should fix this issue.

cheers,
Arnaud
