I don't remember off the top of my head if there were any gotchas to rebuilding NUT on Centos 6.x, but I suspect you can install the SRPM, drop in a newer NUT tarball, update the .spec file, and rebuild. Centos 7 has NUT 2.7.2 in EPEL, I believe.

Right, genericups needs either a physical RS-232 port, or a fully-functional USB-to-serial converter, connected to a contact-closure UPS. Otherwise, the OL status is just reflecting the default state of the floating pins coming into the motherboard serial port.

Indeed.

We thought we had this one solved. NUT 2.7.2 added a driver (nutdrv_atcl_ups) for this device: http://news.gmane.org/find-root.php?message_id=52B4C54E.1050106%40ariwainer.com.ar

However, this "ATCL FOR UPS" string might be for a generic USB-to-serial chip, in which case the nutdrv_qx driver (subdriver fuji) might work better: http://thread.gmane.org/gmane.comp.monitoring.nut.user/8808/focus=8812 (merged and first available in NUT 2.7.3)

I've been pondering setting up some CentOS VMs, but that might be a while. Let us know if you need additional information on rebuilding the RPMs.

Also, what does 'lsusb -v -d0001:0000' return when run as root?
