I can build my own drivers, but unfortunately I still cannot write them. I'm just trying to understand what pkg to build in the indi-3rdparty archive in order to have the Pegasus Focus Cube v2 working in Kstars/Ekos.

Other old topics I found mention the DMFC driver but I cannot find it in the actual indi-3rdparty repo. Same for the debian tgz or custom built pkg linked here . Is there a deb file I can download somewhere? I'd still prefer to compile from the indi-3rdparty github but any other option would work as well.

I have same focuser and my system Raspberry pi 4 4Gb work's fine. only tries the focuser in the list and no more.
sorry for my bad inglish.

The focuser files are not in the 3rd party but in the INDI-drivers section github.com/indilib/indi/tree/master/drivers/focuser

Sorry for the late reply but I wasn't able to check the pc until now. The Focus Cube works out of the box with the default (and built-in) driver. I wasn't used to find something working without me having to install or tweak something so I didn't even check (or thought about checking lol)
