Trouble with Liebert PSI5-1500RT120LI

[darconeous]

I recently purchased a Vertiv Liebert PSI5-1500RT120LI (Admittedly not listed as an officially supported UPS), and after reading this thread I assumed that simply adding something like this to my /etc/nut/ups.conf would do the trick:

[ups]
driver = usbhid-ups
port = auto
desc = "Libert PSI5 (Rack)"
productid = 0002

And this did kinda work, except that it only reports that it is always "on battery". I haven't tried running it down to see if it ever gets to the "LB" condition.

I'm a software developer and I'm not afraid to try hacking around to get this to work, but I'm not sure where to start. Any advice or pointers would be welcome.

Here is the output from running usbhid-ups -DDDDD -a ups manually:

$ sudo -u nut /lib/nut/usbhid-ups -DDDDD -a ups

I see a bunch of timeouts on the "get_interrupt", which I suspect is part of the problem. Any ideas?

A few additional notes:

• That libusb_get_report: error sending control message: Operation not permitted seems suspicious, but running it directly as root doesn't seem to make a difference.
• This is running on a Raspberry Pi 4 with the latest Raspbian. I understand there have been some problems recently with NUT and this platform. Could this be related?

As a separate datapoint, I tried hooking up a cyberpower CP550HG and it worked fine via USB, so I'm hoping this isn't an RPI-specific issue.
