So Subsurface has about half a dozen contributors who don't even dive.
And there are several diver/programmers out there who have shown
tremendous energy and patience to help with topics that don't affect
themselves directly.

I certainly am more than happy to dig into adding support for dive
computers that I don't own. I believe I added to the Atomics Cobalt -
which I don't own :-)

But it doesn't scale.

Is there a public list of which dive computers are missing but we have
data? And a quick "how to get started"?

OK, I think there are a few more "real" USB devices coming in the near
future. So let's figure out what it takes to support that family of
devices.

So this is the "what do we have" part.
What's the "what's missing" part - i.e., where is the starting point to
add support? Or is this entirely new to libdivecomputer and needs to be
designed from scratch?

So I assume you have contact to a few people who have such computers?
