the following command, as root and after having stopped NUT:<br>

Problem is that user.log gets too much logs, whereas everything seems to
work fine (data can be obtained from ups, if ups is disconnected from
electrical system server gets correctly shutdown after a while and so
on)<br>
but in user.log is lot of lines like these at below (two lines are
generated in every second or two)</p>

...<br></p></blockquote><div>these messages from the kernel, related to USB interrupt (possibly timeout):<br>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.<br>
<br>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:<br><br>[Eaton3s]<br>
driver = usbhid-ups<br>
port = auto<br> pollonly<br>
desc = "Serveri UPS"<br><br>the should remove the above log message (if it's really related to timeout), but will decrease reactivity WRT status changes.<br>Another option may be to look at the kernel logging level.<br>

<p>-- after lot googling, best idea is that protocol with UPs is broken?
Can I do smth to help to fix it?</p>
