Hi folks, I've now a new "usb-thing" attached to a CentOs 4.3 box in my room and just followed these steps to get it up and running, hope it helps. [root at sparkbox ~]# cat /etc/yum.repos.d/mgeups.repo [mgeups] name=MGE UPS SYSTEMS baseurl=http://opensource.mgeups.com/rhfc/ gpgcheck=0 # yum install mgeups-psp Now plug the ups and check that: [root at sparkbox ups]# lsusb | grep MGE Bus 003 Device 002: ID 0463:ffff MGE UPS Systems UPS I had to restart hotplug to get the following working: [root at sparkbox ~]# newhidups -a mgeups Network UPS Tools: New USB/HID UPS driver 0.23 (2.0.2-pre2) Detected an UPS: MGE UPS SYSTEMS/ELLIPSE Then, go to /etc/sysconfig/ups and: MODEL=newhidups DEVICE=mgeups OPTIONS="-a" UPSD_OPTIONS= Just verify that /etc/ups/ups.conf has something like this: [mgeups] driver = newhidups port = auto desc = "SparkBox ellipse ASR 1000 VA managed unit" And that's all if you use the standard config providen by the MGE folks, [root at sparkbox ~]# service ups start Iniciando newhidups: [ OK ] Iniciando upsd: [ OK ] Iniciando monitor UPS (master): [ OK ] Check syslog: Mar 24 11:56:13 sparkbox newhidups: Network UPS Tools: New USB/HID UPS driver 0.23 (2.0.2-pre2) Mar 24 11:56:13 sparkbox newhidups: Mar 24 11:56:13 sparkbox newhidups: Detected an UPS: MGE UPS SYSTEMS/ELLIPSE Mar 24 11:56:13 sparkbox newhidups: Mar 24 11:56:16 sparkbox newhidups[5869]: Startup successful Mar 24 11:56:16 sparkbox ups: Iniciación de newhidups succeeded Mar 24 11:56:16 sparkbox upsd[5872]: /etc/ups/upsd.conf is world readable Mar 24 11:56:16 sparkbox upsd[5872]: Connected to UPS [mgeups]: newhidups-auto Mar 24 11:56:16 sparkbox upsd: Network UPS Tools upsd 2.0.2-pre2 Mar 24 11:56:16 sparkbox upsd: Synchronizing...
