RE: input: elantech.c: adding more Fujtisu notebooks to force crc_enabled

["洪一竹 " <sam.hung@emc.com.tw>]

Dear Vincent:

No,boot dmesg is not needed.
But I need cursor move log!

Please follow below steps and get log file:

Step1.find device node
$cat /proc/bus/input/device

Example:
Name: "ETPS/2 Elantech Touchpad"
/devices/platform/i8042/serio1/input/
----------------
Step2. Open debug function.
$sudo su
$echo 2 > /sys/devices/platform/i8042/serio1/debug
----------------
Step3. Put your forefinger on Touchpad and move.
----------------
Step4. Confirm the correctness of the information.   example message:  psmouse serio1: elantech: PS/2 packet[..]…
dmesg
----------------
Step5.save log message
dmesg >> fingerLog.txt
---------------
Step6.send fingerLog.txt file to me.
---------------

I really appreciate your help.

BR,
Sam

My Laptop is a Fujitsu E554 with Elantech Touchpad and trackpoint.
The touchpad works correctly since Rainer's patch.
Do you still need the boot dmesg ?
With or without the patch ?
