Add-on stopped recognising UPS

[fi-sch]

Problem/Motivation

NUT add-on stopped recognising my UPS that is connected via USB. Won't start.
I'm creating a separate issue as I'm not sure what caused this behaviour – I recently updated HA Core, Supervisor and HassOS and noticed that issue after a couple of days.

I tried different "paths" for device instead of 'auto', but it did not help at all. I am running out of ideas.

Expected behaviour

NUT starts up properly as it was before.

Actual behavior

Add-on log below. Please note that device is visible on hardware list in Supervisor -> System panel.

No supported devices found. Please check your device availability with 'lsusb'
and make sure you have an up-to-date version of NUT. If this does not help,
try running the driver with at least 'subdriver', 'vendorid' and 'productid'
options specified. Please refer to the man page for details about these options
(man 8 blazer_usb).

Obviously, I also found this in Supervisor logs:

21-02-08 08:46:43 WARNING (MainThread) [supervisor.addons.validate] Add-on config 'auto_uart' is deprecated, use 'uart'. Please report this to the maintainer of Network UPS Tools
21-02-08 08:46:43 WARNING (MainThread) [supervisor.addons.validate] Add-on config 'devices' use a deprecated format, the new format uses a list of paths only. Please report this to the maintainer of Network UPS Tools
