Hello. First time posting to a Linux ML, new to drivers in general.
So I got an ASUS PU551LD laptop and quickly found out Linux 3.18.3 wasn't
detecting the touchpad correctly. After some digging, I figured out that it is
an ElanTech touchpad which reports firmware version 0x480f0a, then poked
around in drivers/input/mouse/elantech.c and tried changing
'elantech_is_signature_valid' to always return true. This made the device work
properly with all the expected features, and it shows up in dmesg like this:
psmouse serio4: elantech: assuming hardware version 4 (with firmware version
0x480f0a)
psmouse serio4: elantech: Synaptics capabilities query result 0x40, 0x17,
0x0c.
input: ETPS/2 Elantech Touchpad as /devices/platform/i8042/serio4/input/input8
Now of course I want to help getting support for this particular model into
the kernel, but I would feel bad about posting a patch that just adds more
magic numbers to the function in question. Any suggestions?
