I've given up after an hour as well. :(

This remembers me why I normally have only short term branches and do
even rebasing on them. Of course this has other disadvantages like
loosing history. :(

Agreed. It might still be possible to get this sorted out, but after
both of us spending time on it I think it is not worth the effort.
Better use the time for more productive things. :)

Now for the review. I'm hapopy to see that they at least have choosen
a different DFU version to distinguish DfuSe from standard DFU. I
still need to get out the spec from the windows driver package to read
up on it, but I trust you on this part anyway. I'm also happy to see
how minimal the impact in main.c is to support this extension. (Thanks
to all the ground work you did earlier).

So, all in all I'm happy to get this merged. Test with my devices
showed up no regressions. I pulled it into master and if no problems
show up the next days will make a new release later this week. Thanks
again for this major contribution!

I wonder what would be the cheapest/easiast available device using DfuSe and
being compatible with your implementation. A full pocket oscilloscope might
be a bit overkill for playing with it. Any cheap devel board available
having the DfuSe enabled bootloader installed?
