[Nut-upsdev] Tripplite_usb

[Wallis, Chase Civ USAF AFMC 519 SMXS/MXDEA]

He everyone,

 

 

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.

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?
