Hi all,

thanks for the analysis and explanations. From what I have read and
tested, here is a resum=E9 of the Logitech V270 situation :

- Logitech ignore Linux (this is not new, but need to be repeated)
- the V270 mouse basically works as expected HID input device, but is
overly sensible (probably due to its high resolution)
- the mouse events go into /dev/input/mice by default
- if evdev is loaded, mouse events go to /dev/input/event{1..N}
- udev doesn't have the info to create a rule in 10-local.rules so the
V270 get mapped to a fix name like /dev/input/v270
- none of the tools I tried (locomo, logitech-applet) know the V270 for
now. I tried to change some of them, but failed, due to lacking know-how
in HID/USB/etc
- KDE control center or xset cannot reduce the mouse sensibility enough
to make it usuable (at least for my 40 years muscles control ability)

There is some hope to make all this work, with new kernel, xorg and udev
versions. Stay tuned :-)
