I’m going to guess this has something to do with permissions to the device. I obviously can’t see into your environment, but I would get some output by running your software from the CLI first, and see what it says when you’re trying to use it and try to catch and error related to it not being able to talk to the device. You could also try running your software as sudo as a test, but that may just get messy.

Check your groups and see if the device software made a dedicated group for itself, and add your use to it, then see if anything changes.

Also couldn’t hurt to review their docs, or post a link here so people could also review them and see if any steps may be missing.

One other thing to remember is that Debian != Ubuntu. Ubuntu is based on Debian, but wildly different under the hood in some very specific ways, especially when taking a desktop environment into consideration. This software may only work in Gnome, for example.
