Hi, one Fedora user has seen the same (or similar) problem with triplite_usb. After several power cycles ups driver goes crazy, probably hangs. More info and log messages can be found here: https://bugzilla.redhat.com/show_bug.cgi?id=575875 if you are interested in any info, let me know and I'll ask the reporter.
