[Let's move this over to the NUT-upsuser list, since we are not discussing source code. (The post you quoted was from a time when usbhid-ups was still under heavy development.) Thanks!]<br>

Hallo,<br>
<br>
Following the tips found at <a href="https://calomel.org/nut_ups.html" target="_blank">https://calomel.org/nut_ups.html</a> I was trying to<br>
make NUT operate "APC Back UPS CS-350". The device introduces itself as:<br>
<br>
#v+<br>
ugen0 at uhub0 port 1 "American Power Conversion Back-UPS CS 350 FW:807.q7.I<br>
USB FW:q7" rev 1.10/0.06 addr 2<br>
#v-<br>
</blockquote>

So far, so good - the kernel sees it as a ugen device (versus uhid), which allows libusb to talk to it.<div class="im"><br>

My config:<br>
<br>
#v+<br>
[apc]<br>
driver = usbhid-ups<br>
port = /dev/ugen0.00<br>
pollfreq = 60<br>
desc = "Back UPS CS-350"<br>
#v-<br>
<br>
<br>
Unfortunately, when I'm trying to start UPS driver, it's complaining:<br>
<br>
#v+<br>
# usbhid-ups -a apc<br>
Network UPS Tools: 0.29 USB communication driver - core 0.33 (2.2.2)<br>
<br>
No matching HID UPS found<br>
#v-<br>

By default, running a driver as root will drop privileges to whatever user you set in the ./configure script (default: nobody).<br>
<br>
This post reports success on FreeBSD by adding "-u root" to the command line:<br>

Not a good strategy for the long run, but it will let you see if things work.<br>
<br>
This email talks about using devd on FreeBSD to change permission on all of /dev/ugen[0-9]*:<br>

<br>
I don't know if OpenBSD has something similar to devd, but the same principles should apply - libusb probably needs permission to the base /dev node for scanning the bus.</blockquote></div><br>just to add my cents here: iirc, there was also a need to set privileges on the bus, and not only on the device... we will have to track this to complete the user manual.<br>
