It looks like that made it work 😉

I highly recommend updating the instructions here[1]. And also it might help to inform people who package it for various distros. [1]https://timothycrosley.github.io/streamdeck-ui/

The usb library dependency stuff is quite a nightmare to be honest. I’ll try explain it as best I can here for future reference:

Version 1.0.2 of streamdeck-ui uses version 0.6.3 of the streamdeck python library. This v 0.6.3, would “detect” which python library you installed for communicating with the streamdeck device. It would be either hid or hidapi. Some nuanced issues can crop up, mostly if you have both libhidapi-libusb0 and libhidapi-hidraw0 installed. The libhidapi-hidraw0 library is not compatible with all stream decks but libhidapi-libusb0 is, but sometimes it would pick the wrong one.

Fast forward to today: Version 1.0.3 (currently being worked on) uses version 0.8.3 of streamdeck. It no longer requires a python library to provide communication to the streamdeck device. Instead, it directly accesses the LibUSB HIDAPI Backend. That work started here.

TLDR: In the upcoming 1.0.3 release you just need libhidapi-libusb0 installed. It should work even if you had libhidapi-hidraw0 installed (it will choose the right one).
