[Nut-upsuser] [EXTERNAL] Tripp Lite AVR900U

[David Zomaya]

I can confirm there was a protocol change somewhat recently for this model.

It should still be HID-PDC compliant, so I believe it is possible to get it working. Others on the mailing list probably have some useful ideas.


I'm still remote so my ability to run tests for non-networked devices is somewhat limited.

If there's any info I can provide from the Tripp Lite side that we don't already have, feel free to ping me.



Thank you,

Hello! I am currently having issues monitoring a Tripp-Lite AVR900U. First, here are a few system details:

> Manjaro Linux - kernel 5.4.30-1

> network-ups-tools 2.7.4-5 (built from Arch User Repository)

> (lsusb output) Bus 003 Device 003: ID 09ae:3024 Tripp Lite AVR900U

Contents of /etc/ups/ups.conf:

> [tripplite]
> driver =  usbhid-ups
> port = auto

Contents of /etc/udev/rules.d/50-ups.rules:

> SUBSYSTEM=="usb", ATTR{idVendor}=="09ae", ATTR{idProduct}=="3024", SYMLINK+="ups0", GROUP="nut"

Post-configuration, I rebooted then ran upsdrvctl and received the following output:

> $ upsdrvctl start
> Network UPS Tools - UPS driver controller 2.7.4
> Network UPS Tools - Generic HID driver 0.41 (2.7.4)
> USB communication driver 0.33
> This TrippLite device (09ae:3024) is not (or perhaps not yet) supported
> by usbhid-ups. Please make sure you have an up-to-date version of NUT. If
> this does not fix the problem, try running the driver with the
> '-x productid=3024' option. Please report your results to the NUT user's
> mailing list <nut-upsuser at lists.alioth.debian.org><mailto:nut-upsuser at lists.alioth.debian.org>.

I tried adding the following two lines to my ups.conf:

> vendorid = 09ae
> productid = 3024

Subsequent attempts to start the driver fail:

> ...
> USB communication driver 0.33
> Using subdriver: TrippLite HID 0.82
> libusb_get_report: Input/output error
> Can't initialize data from HID UPS
> Driver failed to start (exit status=1)

While the nut website has a report of "AVR900U" support, the productid differs (3024 vs 2010). I can only assume that my particular model uses a different protocol version, unless there is something I missed!

Kind regards,

Mitchell
