Hi i got a macbook air clone netbook e-stary hy-118 with a synaptics touchpad, which is recognized as an alps, the result is that the correct drivers are not loaded and the I can't use it.

So far I have found that in the id sequence it returns 0x02 instead of the expected 0x47 and that results in the touchpad not to be recognized as a synaptics.

I tried to remove the ApplePS2Touchpad kext , and leave only the mouse kext that resulted in erratic motion in the cursor , jumping around , clicking left and right at the same time and finally cursor ending at the left bottom corner of the screen.

At the same time the console register a message ApplePS2mouse :unexpected data received from PS2 controller.

So far i tried voodoo, meklort and apple kexts but same results

Any help will be greatly appreciated.

PS: touchpad works fine under win 7 , xp, and ubuntu using the Synaptics drivers.

yeap I tried netbook installer but since it's based on meklort's kext I had the same results.

For some odd reason this touchpad isn't recognized as a synaptics one (does not return 0x47 code but instead 0x02) and when it falls back to the normal mouse driver it does not function normally , it behaves erratically giving the console error ApplePS2mouse : unexpected data received from PS2 controller" .

I went over the source code of ApplePS2Mouse.kext at www.opensource.apple.com/source and found the piece of code that logs the warning but unfortunately my coding skills are not up to date and can't figure out what triggers that warning.

If someone can have a look up at the file and can explain what is causing this i would be grateful.

ok let me rephrase the question , what kexts are responsible for PS/2 functionality , so far I know

ApplePS2controller.kext , Nub.kext.

Any other that i should check? Why the touchpad is not functioning correctly when the ApplePS2Mouse is used.

Sorry for keep asking But so far I search all over the forums for some info, tried hundreds of kexts but no joy so far, and I feel sorry it's such a nice netbook and everything works except the touchpad.

dorhacker: tried the voodoops2controller.kext 0.98 it says synaptics driver loaded , alps trackpad bla bla bla,

and I end up with a non functioning touchpad.....So if I understand correct it loads the alps driver while i have a synaptics touchpad.....

Update

I want through synaptics touchpad pdf and I found out that my touchpad because it's not recognized as synaptics (because it returns 0x02 instead of 0x47) the driver is not loaded and instead it uses appleps2mouse.kext.

It seems that the touchpad uses the mouse driver somehow in Absolute mode instead of Relative mode because i can see a difference depending on the pressure that been applied on the touchpad while on relative mode the z axis should not make any difference.That would explain also the erratic behavior and the console message that I am getting "ApplePS2Mouse : unexpected data received from PS2Controller" , since the stream of data in Absolute mode is 6 bytes which is different than what the mouse driver expects in relative mode.

Now the question is how can I correct this?

Any help will be greatly appreciated .

ok this thing will drive me crazy , after I tried any kext i could get my hands on with no luck I ended up changing the touchpad with onother synaptics one v 7.2 ,and again i get the same results .

HELP i can't believe that i am the only one that I have this problem........

Well i am using a usb mouse since it's the only way i can move around , the problem is that thse touchpad (s) are not recognized at all and when the ps2mouse driver is loading they behave erratically and i get a message in the console:

"Ps2mouse unexpected data received from ps2controller"
