Peter, What is your opinion on the following idea. I think we can improve the matching a lot, by delaying the exact matcher to *after* parsing the Report Descriptor and applying subdriver specific routines to get to the serial number, model and vendor names. By doing so, we would probably get more accurate information on especially the serial number, since this is located in non-standard

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:

Ha! I got several on and off list requests for details, so I'll give a bunch of details here and then maybe I can move this to a wiki page others can help edit. WARNING! WARNING! WARNING! Be careful! My implementation required opening up high power components, and dealing with 120VAC mains power and high currents on 12VDC. If you decide to tackle any of this yourself, you need to understand

Looks very great, thanks for writing this! I gather you'd port this to the Wiki page you've started, too? A couple of comments: > So I run a NUT server on a Raspberry PI which is connected via USB to my DIY-NAS Arduino. DIY-UPS? > See drivers/arduino-hid.c for the list of supported IDs... Since NUT v2.8.1 [PR #1369], the `usbhid-ups` driver allows the user to specify a

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. Using two straight through wired

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

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
