<p class=MsoNormal>I have a Tripplite SMART700DVa using the tripplite_usb from
NUT 2.5 (rev 2217) driver running in Solaris 10x86. My driver hangs when trying
to connect. Once the driver sends the watchdog command (“W\0”), it can
no longer receive any signals and eventually exits. The UPS responds to other
watchdog commands (“W5” for example), but there doesn’t seem
to be a way to disable it once enabled. From my communication with Tripp Lite,
it doesn’t seem that the SMARTPRO 3003 protocol officially supports
Watchdog. I made some modification to tripplite_usb.c. This modified code
checks which protocol the UPS is using and then resets the watchdog if it is
not SMARTPRO protocol.<o:p></o:p></p>

<p class=MsoNormal>I have had problems with Sun’s libusb, so my issue
might be with that. But I am fairly confident that the SMARTPRO doesn’t
have a watchdog. Does anyone have a Tripplite UPS with the SMARTPRO protocol
that can test this?<o:p></o:p></p>
