When I connect my pinball machine to pc using qflipper on Linux Arch I get this message: “unsupported device found”. I have no problem instead with the app on android. This is the complete log:

Try running the app with sudo:
- Go to the location of the AppImage file in your terminal.
- Run it with
sudo ./<name of file here>

Thank you. I solved the problem by launching the application as root 
OMG Thank you
Thank you !
Uh oh… this really isn’t a solution. I mean, sure it works, but you are giving a program keys to the kingdom by handing it the master key instead of figuring out the appropriate permissions or otherwise.
I don’t have a solution and I’m still on it as I’d rather not run USB issues via root privs.
