Because other things weren't working, I took a lot of pain medication
and then went into Windows and ran the firmware update (after first
installing the driver).

Then I returned to the free state of Debian and did some tests with
stlink2.py -s, things looked good. So I unlocked the core, and I flashed
a version of the firmware that I know worked, and voilà it worked!

So the firmware of the stlink device is an important piece of the
puzzle!
