Subject: i2c_hid module bug
Date: Wed, 24 Oct 2018 20:12:39 +0300	[thread overview]
Message-ID: <e643a163-d5f8-5ca0-c9ba-c6099e35838a@gmail.com> (raw)

Hi! I've catched a bug in Asus FX553VD laptop.

I am really sorry for sending this message to you, but i can't find 
maintainers of this module.

I have ELAN1200 Touchpad, and it's not well managed with hid_multitouch 
module.

So, here are the bugs:

     - Touchpad freezes randomly, which means it dies.

     - When you use two-finger scroll and stop scrolling, module thinks 
that you are still in a scrolling mode. Even if you stop scrolling at 
all and move your fingers away, and try to point mouse anywhere, it 
still thinks that you are in a scrolling mode.

     - Five finger tap kills module. We call it "five finger tap freeze".

     - journalctl is being spammed with i2c_hid errors (3 times per 
second), and it actually influencing on battery life. The message being 
spammed is:

i2c_hid i2c-ELAN1200:00: i2c_hid_get_input: incomplete report (16/65535)

Here's link to bugzilla thread 
https://bugzilla.redhat.com/show_bug.cgi?id=1543769

Hope you will find out where the bug is.

Sincerely, Vladislav.
