Hello guys!

Have a look into the attached email before reading mine, please.

Is it possible to find out about what those bytes are ?
And is it possible to intergrate the support for other
3 bytes into the Linux kernel ?



attached mail follows:


In order to use four buttons the data packages must be larger than the
standard 3 bytes. The data packages that the touchpad sends in absolute
mode is 6 bytes. The information on how the buttons are inserted into the 6
byte packet is proprietary. However, if you would like more information on
the data packets that are sent from the touchpad you can download the
"Synaptics Touchpad Interfacing guide" from our website

I hope this helps,
Fidel Zawde

Can you explain to me, how you inserted 4 buttons into the Ps2 Protocol
I am talking of the touchpad used in the Acer Travelmate 524 TEV.
I want to get access to the four buttons under Linux.
