How does Lauflicht identify launchpads?


I am trying to use a Launchpad with Lauflicht on Linux. When I use the launchpad with Duplex, I can identify the USB connected device in a drop-down that I want to use, and all works fine. When I launch Lauflicht, it doesn’t find the launchpad, and there is no option to specify a particular device.

Does Lauflicht use the USB device ID to spot a Launchpad, Launchpad S and so on? What device IDs is it looking for?
