            When you attempted the shutdown.return, was the UPS powered
            or on battery?  My older Tripplite SMART2200VS won't
            shutdown.return unless it is running off of batteries.  When
            I did try shutdown.return with the UPS powered, the
            tripplite_usb driver showed a similar pattern of
            "libusb_get_interrupt: Connection timed out" messages.

    UPS was powered. Actually, inverter of this particular UPS is broken
    (but undetected by it's logic), so I was unable to test it fully. I
    need UPS free of so called power race condition, however, <br>
    <br>
    10.507657    refresh_report_buffer: expected 3 bytes, but got 2
    instead <br>
    and <br>
    ups.timer.start: 740160<br>
    <br>
    looks suspicious. As you suggest to test it on batt, I'm unsure what
    to do now - get it replaced or exchange to IMPERIAL series. <br>
