3 days ago Another user had a similar issue here: https://github.com/greatscottgadgets/cynthion/issues/169#issuecomment-2282295209 and there's some steps posted in that thread which may fix it. Could you try those out and let us know if it helps?
I have following problems with my cynthion device and packetry. I hope you can help me with that or maybe show me where I can get the help for this. Problem Packetry shows me following message: "This device is not usable because: Failed to claim interface". So I checked the documentation provided on the website and check the hardware connectivity:
C:\Users\X>cynthion info Cynthion version: 0.1.7 Apollo version: 1.1.0 Python version: 3.12.2 (tags/v3.12.2:6abddd9, Feb 6 2024, 21:26:36) [MSC v.1937 64 bit (AMD64)]

When using the pc of my colleague it work fine. I am not sure where my mistake is. I tried following things:
pip install --upgrade cynthion: Works fine (Requirements already satisfied)
C:\Users\X>cynthion setup --check : I get: usage: cynthion [-h] command ... cynthion: error: argument command: invalid choice: 'setup' (choose from 'run', 'flash', 'build', 'update', 'info')
Different USB Connector: No differences
