I don't have a quick answer for you but I'll be in the office later this week and can grab a model with the same protocol and run a test on one of my Ubuntu boxes (which should be close enough to your Pi setup).

Please take a moment and think before clicking any links or opening any attachments from this email. If suspicious, please forward to [email protected] for review. I am kinda stuck on this one. Whenever I attach (USB to a linux box) my TrippLite UPS, it "REMOTE SHUTDOWN". This is a new problem that has cropped up in the last 6 months. At first I thought it was a NUT configuration issue, but now I believe this to be some kind of kernel bug? When I plug in the UPS, I can see the system logs show the UPS, then everything powers off. UPS LCD shows the below error when I plug in the USB cable: "OUTPUT OFF" "REMOTE SHUTDOWN" I tested this against 2 different X86 boxes and a Raspberry Pi. All cause the same result in the UPS. Only one box (nas) has NUT installed and configured. UPS is a Tripp Lite SU3000RTXLCD2U. I am totally stumped on this one. Below is a dump of basically all my specs. Any ideas? -Adam root@nas:~# uname -a Linux nas 5.4.78-2-pve #1 SMP PVE 5.4.78-2 (Thu, 03 Dec 2020 14:26:17 +0100) x86_64 GNU/Linux root@nas:~# cat /etc/nut/nut.conf MODE=netserver root@nas:~# cat /etc/nut/ups.conf [ups1] driver=usbhid-ups port=auto root@nas:~# cat /etc/nut/upsd.conf LISTEN 127.0.0.1 3493 LISTEN 10.1.1.2 root@nas:~# cat /etc/nut/upsmon.conf root@nas:~# cat /etc/nut/upssched.conf root@nas:~# root@nas:~# cat /etc/debian_version 10.7 Before all this broke, I was able to monitor the UPS and get the following info: battery.charge: 100 battery.charge.low: 20 battery.charge.warning: 20 battery.runtime: 6662 battery.temperature: 29.9 battery.type: PbAc battery.voltage: 81.0 battery.voltage.nominal: 72.0 device.mfr: TRIPPLITE device.model: TRIPPLITE UPS device.serial: XXXXXXXXXXXXXX device.type: ups driver.name: usbhid-ups driver.parameter.pollfreq: 30 driver.parameter.pollinterval: 2 driver.parameter.port: auto driver.parameter.synchronous: no driver.version: 2.7.4 driver.version.data: TrippLite HID 0.82 driver.version.internal: 0.41 input.frequency: 60.0 input.transfer.high: 150.0 input.transfer.high.max: 150 input.transfer.high.min: 145 input.transfer.low: 55.0 input.transfer.low.max: 60 input.transfer.low.min: 55 input.voltage: 123.0 input.voltage.nominal: 120 output.current: 1.9 output.frequency: 60.0 output.frequency.nominal: 60 output.voltage: 120.0 output.voltage.nominal: 120 ups.beeper.status: enabled ups.delay.shutdown: 20 ups.delay.start: 30 ups.firmware: 64 ups.load: 8 ups.mfr: TRIPPLITE ups.model: TRIPPLITE UPS ups.power: 226.0 ups.power.nominal: 3000 ups.productid: 4004 ups.serial: 2620ELCPS87A200020 ups.status: OL ups.test.result: Done and passed ups.timer.reboot: 0 ups.timer.shutdown: -1 ups.timer.start: 0 ups.vendorid: 09ae ups.watchdog.status: 0 root@nas:/var/log# zcat messages.*.gz | grep -i tripp Jan 15 11:05:05 nas kernel: [ 1.571857] usb 3-1: Product: TRIPPLITE UPS Jan 15 11:05:05 nas kernel: [ 1.571858] usb 3-1: Manufacturer: TRIPPLITE Jan 15 11:05:05 nas kernel: [ 1.629210] hid-generic 0003:09AE:4004.0001: hiddev0,hidraw0: USB HID v1.11 Device [TRIPPLITE TRIPPLITE UPS ] on usb-0000:2e:00.3-1/input0 ________________________________ This message is for the addressee's use only.
