[Nut-upsuser] Help with newhidups subdriver for Dynex UPS

Hello everyone!
     If this message was posted twice, my apologies.  I'm having issues with
my webmail today...

I am using the testing version of NUT from SVN at changeset 582.  I have
successfully created a stub for newhidups driver for my Dynex DX-800U UPS, but I
am completely lost on the customization of it.  I've followed the
hid-subdrivers.txt instructions and I understand I need to map all the
"unmapped.*" lines of my dynex-hid.c to NUT functions.  However, I
can't make heads or tails of what I'm supposed to change.  Can someone
take some time to help a struggling noob?  Here's some info I hope helps:

                port = /dev/usb/hiddev0

I've tried running with the generic, cyberpower and cpsups drivers as well,
but they failed to start.  If I can provide any more info, please let me know.

[Nut-upsuser] Help with newhidups subdriver for Dynex UPS

Dear Michael,

it looks like your efforts were unnecessary. The instructions in
hid-subdrivers.txt are intended for devices that are not *already*
supported by newhidups. On the other hand, your UPS was made by Cyber
Power Systems, and is already supported by the APC/CyberPower
subdriver. Note the lines:
> Detected a UPS: CPS/DX-800U
> Using subdriver: APC/CyberPower HID 0.9
You should be able to follow the instructions in INSTALL and get it to
work "out of the box". 

I have also put some instructions, specifically for newhidups, at
http://www.mathstat.dal.ca/~selinger/ups/backups.html
