That's still about 80 devices ... :-o

Cool.

You probably want to be a bit more specific in noting the version you
used ;-)  Rolf's PPA is designed to change.
Just past the version provided by ./configure --version, that is good
enough to find back the exact commit.

I don't really share your optimism about them being minor, exact perhaps
for the first two.  The other ones may or may not be so minor (based on
seeing others wrestle with getting support for higher resolutions right
as well as adding button support).

Based on my own recent experience with fixing the compiler warnings, see
#120, I wouldn't lump that many issues in a single issue again :-/
Splitting them out at the very least makes it easier to see what has
been taken care of :-)

Hope this helps,
