Hi there,
Ups is connected via usb:
Bus 003 Device 002: ID 051d:0002 American Power Conversion
Uninterruptible Power Supply
Recently I noticed that nut stopped to recognize it (probably after
some update):
# /lib/nut/usbhid-ups -a APC
Network UPS Tools - Generic HID driver 0.41 (2.7.4)
USB communication driver 0.33
No matching HID UPS found
# cat /etc/nut/ups.conf
[APC]
driver = usbhid-ups
port = auto
I did try to fix the problem by adding vendor or product options or
changing the driver but no luck.
Any suggestions? Is the driver correct?

Smart-UPS models have two kinds of signal communications - Basic and Smart
Smart signaling offers more functionality and in general recommended to
use by APC.
I'd try to use "apcsmart" driver in nut config. [1]
For other things to try I'd check recent apt installation logs for
installed packages relevant to this case.
Also checking syslog for any clues would be a good place to start and
see how UPS is recognized by the system when connected and what
permissions assigned to it by udev.
