Dear List, I have an MGE Ellipse 1500. I run openSUSE 10.2, kernel
2.6.18, libusb 0.1.12, nut 2.0.5. ps shows that the following processes
/usr/lib/ups/driver/newhidups -a mgeups
/usr/sbin/upsd -u root
NUT operates correctly, shutting down the server after 4 minutes without
power. However I'm seeing 25 to 50 messages logged each day in
/var/log/messages of the form:
Jun 21 16:11:40 pastis kernel: usb 3-1: usbfs: USBDEVFS_CONTROL failed cmd
newhidups rqt 128 rq 6 len 255 ret -110
Jun 21 16:46:29 pastis kernel: usb 3-1: usbfs: USBDEVFS_CONTROL failed cmd
newhidups rqt 161 rq 1 len 2 ret -110
I read in Arnaud's message

Can I ignore these newhidups messages as "background noise"?
I also run the mgeups-psp-3.0.2 front end which shows two or three
"communication failures" each day lasting either 2 or 4 seconds.
Can I ignore these messages as well?
