[Nut-upsuser] Issue with two UPS APC managed from a single PC.

Hi Jim,
Yes both UPS are on the same machine.
I moved away from Ubuntu and tried with Kali and got a slightly different issue as the driver even doesn’t start properly.
I used the standard apt-get command to download nut and added libusb-dev which wasn’t by default on kali.
I went to Kali nut web page and downloaded all packages 😊
hiddev0 and hiddev1 have been created in /dev/usb and changed the group to nut as they’ve been created with root group.
I have attached the lsusb traces for the 2 UPS
When starting the driver I got this message
$ sudo upsdrvctl start
Network UPS Tools - UPS driver controller 2.8.0
Network UPS Tools - Generic HID driver 0.47 (2.8.0)
USB communication driver (libusb 1.0) 0.43
interrupt pipe disabled (add 'pollonly' flag to 'ups.conf' to get rid of this message)
libusb1: Could not open any HID devices: insufficient permissions on everything
No matching HID UPS found
Driver failed to start (exit status=1)
Thanks for your help and guidance.
Laurent

Is that with both UPSes on same machine?
A quick guess would be that insufficient data points to identify the device are configured (vendorid, productid, serial...) in ups.conf, so both drivers connect to the first match. I'd expect them to conflict and one would die or both loop reconnecting, if both are running at once, though.
Also, which NUT version? Custom build from GitHub or an (older?) distro package?
Jim

Hello
Can you please share the configuration you have used, as well as the output of lsusb ?
