Thanks, Mark CentOS 5.4 nut-2.2.0-7.el5 nut-client-2.2.0-7.el5 Upgrade NUT to the latest version first. Loads of changes have been made to the usbhid-ups driver since nut-2.2.0 was released well over three years ago. We no longer support this version. Best regards, Arjen Okay, I upgraded to 2.4.3 and restarted nut. I still get: Oct 20 11:33:16 alkmene kernel: usb 3-1: usbfs: process 16588 (usbhid-ups) did not claim interface 0 before use Oct 20 11:33:48 alkmene last message repeated 43 times Oct 20 11:34:50 alkmene last message repeated 85 timesupgrading NUT is not enough: you also have to stop the old instances and start new ones that use the newly installed version. this remark comes from the fact the PID above (16588) is the same than the previous "faulty" one.
Ah, this is a very good observation of you! I did run a 'service ups restart', but the usbhid-ups process wasn't killed. I had to manually kill it. From now on, a restart of the ups service does restart the usbhid-ups process as expected. Perhaps I should have issued a 'service ups stop' before I upgraded from 2.2 to 2.4 as I expect that the 2.2 /etc/init.d/ups would killed the usbhid-ups process.
Furthermore, the 'usbhid-ups did not claim interface 0 before use' messages now have disappeared. So also Arjen's advice to upgrade was useful :)
Thanks, Mark
