In fact it "half works". I can't click the left button, and the mouse pointer
doesn't adjust properly to the screen context, depending on where the cursor is
located the right button works. For example it stays with the console (text)
cursor when I move the cursor out of the console window.

So not sure if my previous comment was really useful.
I debugged the issue a little further, it seems the mouse is properly detected
by udev as the clicks on all buttons appear in the output of "libinbut
debug-events".
But at the same time the mouse is not listed in the output of "xinput list".
Seems to possibly be related to libinput.

For the TW snapshot I'm not 100% sure which one it was. But I'm upgrading
really often and I'd says that with last week's snapshot it worked.
