Public bug reported: I hooked my new CyberPower UPS: CP685AVR-G on my Lucid server and got this error:
Jan 15 12:06:33 xeon upsd[5441]: Can't connect to UPS [cyberpower] (usbhid-ups-cyberpower): No such file or directory Jan 15 12:06:38 xeon upsmon[5445]: Poll UPS [cyberpower@127.0.0.1] failed - Driver not connected After trying many things, I found https://bugzilla.redhat.com/show_bug.cgi?id=488368 that hint me in the right direction. The required change was to rename the udev rule like this: mv /lib/udev/rules.d/{5,6}2-nut-usbups.rules Now, everything works well, without requiring "user = root" in /etc/nut/ups.conf because the udev rule now ensures the device file is owned by the group "nut": # find /dev/bus/usb/ -ls 1536 0 drwxr-xr-x 10 root root 200 Jan 15 12:40 /dev/bus/usb/ 1579 0 drwxr-xr-x 2 root root 60 Jan 15 12:40 /dev/bus/usb/008 1580 0 crw-rw-r-- 1 root root Jan 15 12:41 /dev/bus/usb/008/001 1573 0 drwxr-xr-x 2 root root 60 Jan 15 12:40 /dev/bus/usb/007 1574 0 crw-rw-r-- 1 root root Jan 15 12:41 /dev/bus/usb/007/001 1567 0 drwxr-xr-x 2 root root 60 Jan 15 12:40 /dev/bus/usb/006 1568 0 crw-rw-r-- 1 root root Jan 15 12:41 /dev/bus/usb/006/001 1561 0 drwxr-xr-x 2 root root 60 Jan 15 12:40 /dev/bus/usb/005 1562 0 crw-rw-r-- 1 root root Jan 15 12:41 /dev/bus/usb/005/001 1555 0 drwxr-xr-x 2 root root 60 Jan 15 12:40 /dev/bus/usb/004 1556 0 crw-rw-r-- 1 root root Jan 15 12:41 /dev/bus/usb/004/001 1549 0 drwxr-xr-x 2 root root 80 Jan 15 12:40 /dev/bus/usb/003 2163 0 crw-rw-r-- 1 root nut Jan 15 12:49 /dev/bus/usb/003/002 1550 0 crw-rw-r-- 1 root root Jan 15 12:41 /dev/bus/usb/003/001 1543 0 drwxr-xr-x 2 root root 60 Jan 15 12:40 /dev/bus/usb/002 1544 0 crw-rw-r-- 1 root root Jan 15 12:41 /dev/bus/usb/002/001 1537 0 drwxr-xr-x 2 root root 60 Jan 15 12:40 /dev/bus/usb/001 1538 0 crw-rw-r-- 1 root root Jan 15 12:41 /dev/bus/usb/001/001 Generic information: # lsb_release -rd Description: Ubuntu 10.04.4 LTS Release: 10.04 # apt-cache policy nut nut: Installed: 2.4.3-1ubuntu3.2 Candidate: 2.4.3-1ubuntu3.2 Version table: *** 2.4.3-1ubuntu3.2 0 500 http://archive.ubuntu.com/ubuntu/ lucid-updates/main Packages 500 http://archive.ubuntu.com/ubuntu/ lucid-security/main Packages 100 /var/lib/dpkg/status 2.4.3-1ubuntu3 0 500 http://archive.ubuntu.com/ubuntu/ lucid/main Packages ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: nut 2.4.3-1ubuntu3.2 ProcVersionSignature: Ubuntu 2.6.32-45.102-server 2.6.32.60+drm33.26 Uname: Linux 2.6.32-45-server x86_64 Architecture: amd64 Date: Tue Jan 15 12:43:46 2013 ProcEnviron: PATH=(custom, no user) LANG=en_CA.UTF-8 SHELL=/bin/bash SourcePackage: nut ** Affects: nut (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug lucid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1099947 Title: driver unable to connect to CyberPower UPS using usbhid-ups driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nut/+bug/1099947/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
