Touchpad issues on Asus Slate (EP121) on Android 3.2

[Toby Foss]

I have a problem on my ep121 (asus slate). I too have tried the "copy
vendor_xxxProduct_yyy.idc Vendor_a001Product_0eef.idc" file fix as
described in multiple posts to fix the problem without success. I have
also tried other Android versions like 2.2.1, 2.2.2, 2.3 as well as
this 3.2 version, all with similar results.

FYI ony: from the command: less /proc/bus/input/devices
Product ID = a001 Vendor id=0eef Version 0210
name:="eGalax_eMPIA technology inc. PCAP Multitouch controller"
from the command: uname - r returns: 3.0.1-android-x86-asus-laptop+"

Specifically, here is the problem I see.... If you use a mouse in the
GUI to go to "apps->developer tools->pointer location" the touchscreen
works there. Touch, multi-touch and swipe all works.

At first I thought it was a driver issue, but the fact the touchpad
works in the developer "pointer location" tool seems to indicate the
driver is fine and the problem is more with interpreting the
touchscreen input from the driver into the Andriod GUI rather than the
touchscreen inputing into the driver. (from the CLI, the command
"getinput" function also shows it can read in the touch events from /
dev/inputs/event14)

I have not been able to fully understand the way the .IDC files and
the "handlers" entries work, but I noticed a "fake touchpad" and the
mouse entries that has an handler entry "mouse" or "mouse1". The
touchpad only has a handler of "event14 kbd"

Just my observations and wondering if anyone else has ever seen this
behavior

Thanks in advance,
Toby

I have an AAO 110 with touchkit/eGalax touchscreen hardware mod. Am
using 3.2 build for eeepc which works mostly fine.

I have the same issues with the touchscreen. I have copied the
qwerty.idc file to Vendor_0eef_Product_0001.idc but no results.

Pointer location in dev tools does not show any activity; the touchpad
on the keyboard works but pointer location shows no change in X and Y
axis, not even for the working touchpad.

I found a new EETI / eGalax driver for Linux kernel 3.0, which is in
Android-x86, as far as I know. Installing it involves rebuilding the
kernel, a task I am not up to. There are lots of eGalax touchscreen
owners who would be very happy if someone of the dev team would look
into this.

Many thanks for helping getting this touchscreen to work!
