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? -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
