Did you need specific additional files for this to work or only the provided examplefile?

[ColinCepuran]

Just this. Installed KoboRoot.tgz without changes and the provided examplefile.

In the provided configuration the larger button advances and the smaller button goes back.

That's awesome. I'm having no such luck with the Kobo Clara 2E. They must be different under the hood somehow I'm afraid.

Can second that this still works great (Libra 2, latest firmware).
