10.04.2018 - emailed message to Asus Customer Service

Dear Asus Customer Service,
I would like to be informed about two most imporant things regarding my Asus 
G752VS laptop:

will Asus release anytime soon the new BIOS update containing Meltdown and 
Spectre fixes?

will this new BIOS update contain a fix for reported long standing ELAN 
touchpad issue and finally make the touchpad usable (wake the dead) under Linux?

Best regards,
worried Customer

Dear Linux kernel developers,
with a hope that this message can somehow help finding the definitive and 
complete solution, I'm writing to inform you about some important news 
regarding Asus G752 laptop series and a long standing ELAN touchpad issue 
(touchpad "ELAN1203:00 04F3:3043" completely dead).

Some people reported in 2017 that installing a "suspicious" file under Windows 
solves the ELAN touchpad Linux problem too:
After a long time thinking, I didn't want to take a risk since the mentioned 
Windows file is "suspicious".

Now the big news is that after executing a few simple commands, ELAN touchpad 
is miraculously awaken from death and it starts partially functioning.
If you have some free time, please take a look here:

Best regards.


Solus deveopers helped me to solve the "bash: new_id: Permission denied"
problem in executing commands suggested by Clément Gayot - and here's
the result:

# cd /sys/bus/hid/drivers/hid-multitouch
# ls
0018:04F3:3043.0007 bind module new_id uevent unbind
# echo "0018:04F3:3043.0007" | sudo tee 
# echo "0018 04F3 3043 0013" | sudo tee 

Miraculously - touchpad mouse and buttons works ok (as Clément Gayotbut said, 
no solution for multitouch - no gesture capabilities for Elan Mouse). Fn keys 
to disable and enable the touchpad works, but produce no effect at all - 
touchpad is always enabled.
Both with xinput and libinput-devices, two devices are now listed:
