Troubleshooting • Re: USB not recognizing UPS attached to USB 2.0 or 3.0 ports

Ok I tested with a powered USB 2.0 hub and not the USB device is showing up in LSUSB:

admin@NSO-PI:~ $ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 006: ID 046d:c077 Logitech, Inc. Mouse
Bus 001 Device 004: ID 17ef:6099 Lenovo Lenovo Traditional USB Keyboard
Bus 001 Device 007: ID 1a40:0101 Terminus Technology Inc. Hub
Bus 001 Device 005: ID 051d:0003 American Power Conversion UPS
Bus 001 Device 003: ID 1a40:0101 Terminus Technology Inc. Hub
Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

However dmesg is still ALSO throwing an error (but only once now instead of repeating) and the device is inaccessible:

Any ideas on what’s going on or how I can more troubleshooting?

We have ultimately, works fine on Mac and Windows (shows up as external UPS), doesn’t work on Raspian specifically pi 4B. I also verified that this pi is affected by the circuit board e-mark issue. Can only get power when plugged in with non-emark cable….. could this somehow be playing into this since the UPS shows up as an external battery? Does anyone know if usb a to usb b cables are emarked? I couldn’t tell….
