The error message shown is a bit vague. You need "libhidapi-libusb.so.0", which is part of libusb but is typically provided under it's own name: libhidapi

For Ubuntu this snippet should work:

apt-get install libhidapi-libusb0
ln -sf libhidapi-libusb.so.0.0.0 /usr/lib/x86_64-linux-gnu/libhidapi-libusb.so.0

libhidapi-libusb0 is already installed and the symbolic link already exists too

I'm seeing this as well and satisfy the conditions;

cat /etc/lsb-release

what I did to fix things, was run

pip-review --user -a which updated a bunch of python stuff, complained about a streamdeck ui streamdeck-ui 2.0.15 requires pillow<10.0.0,>=9.4.0, but you have pillow 10.2.0 which is incompatible

so I redid a local virtualenv poetry config virtualenvs.create true then re-ran pip3 install --user streamdeck_ui

and now it works again.

Thank you ! It works perfectly for me too now !
