The Lenovo T60 actually has a touchpad, a trackpoint and three buttons,
where the Lenovo X60 only has a trackpoint and three buttons.
Searching the Web with this message, there are also hits for other
laptop models.
Looking at `drivers/input/mouse/alps.c` the values checked there for E7
and EC are not related at all. It’s also interesting that E7 and EC
contain the same values.
Is that the trackpoint device detected later and should therefore be
ignored?
Thanks,
Paul
