Where do I find those three values mentioned in the third column? And is
that line important at all? I just did below patch as a drive-by-patch
and from looking at the source code I can't immediately spot how to get
them :-/
FWIW, it's a 2 hw buttons touchpad and I saw this in dmesg
psmouse serio2: elantech: assuming hardware version 4 (with firmware
version )
psmouse serio2: elantech: Synaptics capabilities query result 0x50,
0x12, 0x09.
psmouse serio2: elantech: Elan sample query result 01, 27, 86
Are those values from "Elan sample query result" what you are looking
for? Then the line would be:
Fujitsu LIFEBOOK E547 0x470f00 01, 27, 86 2 hw buttons
