Has anyone used #Overwitch, the #Elektron #Overbridge device client for Linux?

I'm having problems getting it to work. It compiled ok (just the cli, but that's ok), and the additional udev-rules has been installed. I've restarted the computer to be on the safe side. I've selected "overbridge" mode in the #Digitone's USB-config.

`overwitch-cli -l` says nothing, actually any `overwitch` command just returns without any message (although with the return code 1).
`lsusb` finds the device.
