no, the CCD debug functionality is in the Google security chip (CR50) which
detects the special debug cable (https://www.sparkfun.com/products/14746 --
schematics linked) on a specific port and then enables the features
according to the CCD state (open/locked)

Hello!
It wasn't a question. Not really. I was asking the group at-large to
see how many of us are aware of them things. You, Matt, were the
first. And on the document that I mentioned that the Sparkfun page has
linked, describing what devices were supported, and naturally were
not, at the bottom was one of us also., see here
https://sites.google.com/a/chromium.org/dev/chromium-os/developer-information-for-chrome-os-devices

It turns out that the page you referenced, is also there, it is where
everything on the subject migrated to.

As for me, I am leaning towards two things, one of obtaining the
cable, and two is obtaining one of the known working devices. My
problem is that the model I met the same day I bought this guy, is not
listed. It's the Dell Chromebook who's advertiser was a Classical
Music fan. (He or they used a Beethoven Rondo, "Rage over a lost
penny") it was well done and seemed to be choreographed to the music.

Soon I hope. However I have WSL enabled on this machine, can I use
that to build but not necessarily run the Chrome OS images that the
Google folk want us to build and try out? As for on what I'm still
thinking of what for that.

sorry, what exactly is your question?  I have one of these cables, works
great for flashing/debugging Chromebooks via CCD

the updated Chromium CCD docs can be found at:
