[Nut-upsuser] NUT 2.8.0-7 with Rasp Pi5 bookworm error driver

Note that stopping nut-server.service does not impact your ability to
run/restart the drivers, see docs on NUT 3-layer architecture for more
details.

The single nut-driver.service was last delivered with NUT v2.7.4; now it is
a multi-instance nut-driver at YOURUPSNAME.service with magic done by
nut-driver-enumerator* units. You should stop those units before
experimenting with e.g. direct driver program launch for
debug/troubleshooting.

Also don't use the old upsdrvctl on OSes with systemd or SMF, use
upsdrvsvcctl instead if you must :)

Did you literally write that? Which driver, we have about 50?

e.g. with Debian-ish packaging it might be /lib/nut/usbhid-ups or what
suits your UPS.

Hope this helps,
Jim Klimov
