Can you provide a pointer to details on the usbhid-dump tool? Not
familiar with that one.
I'm using Ubuntu 14.04 Server on an i686 Dell/Wyse CX0 thin-client -
usbhid-dump was available as part of usbhid-utils, if I am not mistaken.
https://github.com/DIGImend/usbhid-dump
Depending on how much of the Power Device Class (PDC) HID spec they
have implemented (rather than doing non-PDC HID as a cheap
USB-to-serial replacement), this might require a separate driver, or
it might be easy to extend usbhid-ups. The "explore mode" mentioned
in the link below will provide the output to guide that decision.
I do have the correct permissions for udev. The explore mode complains:

I've ordered a second model (EBay, $25) - one to install into the car,
and one to debug/test. It is possible to change some of the parameters
of the device, using a Windows program. I have another CXO host with
Windows on it that runs the Copeland Engineering software, with which I
can compare if necessary.
I expect it won't be hard to get this working with nut, and I'm happy
to do a bunch of legwork (commit credits!) in order to get this thing
working for my purposes - and I appreciate your help, Charles.
