...y reject devices (also, depending on whether a subdriver supports this) if they are not a UPS. We could easily check for this in the HID tree. This in turn could mean that we can be far less strict on matching the ProductID, since we could reject devices that don't report themselves as a UPS or Powerdevice. Any thoughts on this? Could this be worthwile to investigate further, or am I missing something vital here? Best regards, Arjen

I used this command to create volume label on OCFS: mkfs.ocfs -F -b 128 -L data13 -m /oradata/data13 -u oracle -g dba -p 0775 /dev/emcpowerp1 emcpowerp is composed of /dev/sdad and /dev/sdk. It seems the above command created the same labels for /dev/emcpowerp1, /dev/sdad1 and /dev/sdk1. But when I tried to mount this ocfs filesystem by label, it gave me the following error. # mount -L data13

While working on the mge-hid subdriver, I wanted to add the 'beeper.mute' command. Unfortunately, the description I intended to use was used already by the 'beeper.off' instcmd: CMDDESC beeper.off "Temporarily mute the UPS beeper" Now of course we could add another instcmd 'beeper.reallyoff', but instead I would prefer to bite the buller and do the following:

...ing NUT. The RPi is powered by the inverter, and it powers the Arduino over USB. The RPi stays on during a power outage. So now I can write some Arduino code that loops and checks the status of a digital pin. How do I pretend to be a UPS in a way NUT will recognize? Some googling led me to the HIDPowerDevice project. https://github.com/abratchik/HIDPowerDevice. That is a library for Arduino MCUs that does all the protocol for getting an Arduino device to be recognized as a HID compliant UPS device over USB. You use it by periodically calling a `sendReport` function with various flags set. Ex: PowerDevi...

Is anyone using a 3com 3CNJPSE to power a 7960G? I have a couple of 7960Gs and 3CNJPSEs but no combination appears to work. Both phones work fine with a cisco power cube. I get a 47.6V reading across pins 5 and 8 on the patch cable coming from the 3CNJPSE. The network still works through the 3CNJPSE, just no power to the phone until I connect the power cube.

Hello all, Now that I am subscribed to the list I can reply at last :) Kelly, thank you for the comprehensive write-up and pointers to sources and the Arduino lib and example. This took me into a rabbit hole and I've spent entirely too many hours browsing through the NUT sources and USB/HID/PowerDevice specs. Jim, thanks for the comprehensive write-up and all the work you do on NUT. This project has definitely accumulated heaps of wisdom in-between the source lines over the years. The picture is much clearer now, and the scope of the effort also. Not an easy feat! I wish I had cycles to spare....

Hello all, I think there was a very good reply about an Arduino-based controller for a DIY UPS here. The project you posted to, with an Arduino presenting as a Megatec protocol server, also seems interesting. Here I'd like to reply to one point not covered before - DMF. As a short and quick reply - unfortunately no, you can not use it with stock upstream NUT at the moment, and not for
