these messages from the kernel, related to USB interrupt (possibly
timeout):
we get data from the devices through explicit requests (polling) and
interrupt. Interrupts are notifications generated by the device, upon
data change, without requiring any explicit request.
there is nothing we can do in NUT. The only thing for you would be to
disable interrupt, by adding "pollonly" to your ups section in ups.conf:
[Eaton3s]
driver = usbhid-ups
port = auto
pollonly
desc = "Serveri UPS"
the should remove the above log message (if it's really related to
timeout), but will decrease reactivity WRT status changes.
Another option may be to look at the kernel logging level.
Thank you! Adding "pollonly" helped, and no more messages in logs.
Little question still stays - even if exclusive access is used, why so
many messages (there are lots of USB devices around nowdays, don't know
about exclusive access used to connect to them, but I have never seen
such logging before.).
