[Nut-upsuser] Tripplite SMART2200VS with tripplite_usb: UPS doesn't shut down

Please ignore the previous message as I sent it before it was complete.

Hello,

I have a Tripplite SMART2200VS that isn't being shut down when the nut
master asks it to.  My initial test was simply upsmon -c fsd which did
cause the system to shut down, however the UPS remained on and providing
power to its loads.  Looking in the logs (daemon and syslog) it was not
clear to me that NUT was actually telling the UPS to shut down (I was
expecting to see "Shutting down the UPS ..." in the logs based upon
/etc/init.d/nut-server).  Since I installed from packages rather than
source, and I could see the init scripts had support for the poweroff
command which calls upsdrvctl shutdown, I made the assumption that the
system is probably properly configured, but there may be a communication
issue with the UPS.  (may or may not be a logical assumption)

Next, I provided non-UPS power to the NUT master and shut down all the
loads connected to the UPS.  I then manually issued the shutdown via the
driver (/lib/nut/tripplite_usb -a tripplite -k -DDD) but the UPS still
remained up.  I don't know enough about NUT to debug this completely, but
my hunch is that the problem is with the communication between the driver
and the UPS, I'm just not clear on how to debug further.

Thanks for any additional assistance and insight!

The UPS never shut down.

The delay command ('N') was sent successfully, so the UPS is receiving
commands.

Is the unit on line power at this point? I don't think we know the command
needed to power off the UPS when it is not running on battery (the 'G'
command seems to be "wait for power to return"). I suspect we could
emulate it with the watchdog, but that will require a fair amount of testing to
make sure we understand the timer.

Yes, the UPS is on line power and the NUT master is not powered by the UPS
for the test. The libusb_get_interrupt() messages continued well past the
64 second timeout.

So the current NUT can't cause this UPS to power off the load while it is
on line power, correct?  I will update the nut-server init script with the
sleep/reboot logic per FAQ #51.

My larger concern is testing the UPS to ensure it shuts down correctly and
comes back up correctly as well.  My concern is driven by my observation
that with older versions of NUT using the tripplite_usb driver, this UPS
has *not* correctly shut down while on battery, thus the batteries drained
and the UPS never supplied load power once line power had been restored.  I
assume the next logical test would be to do the same test
(/lib/nut/tripplite_usb -a tripplite -k -DDD) while the UPS is on battery?

Are the serial drivers any better at this sort of thing than the USB driver
for these older Tripplite UPS systems?
