ps2/ new data for mouse protocol (fwd msg attached)
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 ?
Sincerly,
Nico
Hello,
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 www.synaptics.com.
I hope this helps,
Fidel Zawde

Subject: informations needed of touchpad
Hello!
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.
Sincerly,
Nico Schottelius

So they put information about four buttons in six bytes and call that proprietary? ROFL! How hard can it be? I think it will be fairly straight forward to reverse engineer the format, it can't be rocket science.

No need for this, just read the public available documentation !
Proprietary != Secret.
However, some mouse secrets from various sources I hacked in here: http://home.t-online.de/home/gunther.mayer/gm_psauxprint-0.01.c

Very nice. I am currently looking for some info to solve a problem with thinkpads and logitech cordless mice over ps/2. Basicly the wheel doesnt work. Looking closer they dont respond to the imps/2 or mousemanps/2 protocol. Since cordless mice are more common than thinkpads, I think the problem would be solved if it was with the mouse. So I am guessing the IBM defaults to just repeating standard ps/2 protocol, and you have to first trick that before you trick the mouse. Since it works in windows there IS a way...
Where do I find the public available protocols, and the secrets? :)
And for the list, who should I notify that I am working on autodetecting IBM thinkpad ps/2 repeaters in mouse driver?
(And yes I know some of the work belongs in XFree and gpm)

Actually I'm interested in this work. We have input api drivers for PS/2 devices so it would be easy to add support. Any info would be helpfu to expand the devices we support.
Hi Allen,
I received your following message since James Simmons CC'd it to the linuxconsole-dev mailing list:

recently I spent a lot of time figuring out how to make a chordless wheel mouse, which had two extra buttons on the left and on the right, work on Linux with gpm and XFree86 4.0.3. The mouse was supposed to support both the IntelliMouse and IntelliMouse Explorer protocol extensions, but no matter which protocol selection I tried with gpm, the mouse would stick in its 3 byte standard PS/2 mode. The same happened without gpm, when I tried to use the mouse with XFree86's "ExplorerPS/2" setting.
After many hours of research I finally discovered why. The initialization sequence used by both programs is not exactly what the mouse needs:
- XFree86's "ExplorerPS/2" setting sends an initialization sequence of
{ 243, 200, 243, 200, 243, 80 }. For this mouse, however, the sequence
must be { 243, 200, 243, 100, 243, 80, 243, 200, 243, 200, 243, 80 }.- The initialization sequence used by gpm 1.19.3 includes the byte 246 which is meant to reset some mouse settings back to normal. However, for this mouse, it also resets it to 3 byte standard PS/2 mode.
I already submitted a patch to the XFree86 team, but don't know whom to contact for the gpm fix.
I hope this helps you with your mouse!

PS1: A good reading for mouse related stuff is Adam Chapweske's page at
http://panda.cs.ndsu.nodak.edu/~achapwes/PICmicro/mouse/mouse.html.
PS2: FWIW, my mouse is a NEO AirView 405 RF, which is a OEM product sold in Germany under multiple brand (at least Neolec, Typhoon, Dexxa) and product names (see e.g. http://neolec.de/news/indexAirView405RF.html).

Can you help me do that, Erik ?
