Just looked at some things on google and looks like the E5430 actually has a different model. It's identifier is 0x73, 0x03, 0x0a, also the protocol version is v4 instead of v3 like the one I have. So as it stands right now it won't work.

 

However, I am trying to get it working for all the different protocol versions...a complete port of the alps driver in linux. Give me a few days or so and I might have something for you to try out.

So I took some time to get a working touchpad driver for the touchpad in my Latitude E6520. This driver is based off of the one by ReHabMan. Source: https://github.com/bpedman/OS-X-Voodoo-PS2-Control

Sounds like a brilliant contribution, many thanks for this!

miguelme777, seems to me you have the exact same hardware as I have: E7=0x73 0x02 0x64, EC=0x88 0x07 0x9d   What laptop model do you have? Do you get the same error message as I got?  Jun 3 09:32

Yeah, just your kext loading:

And when running the debug version, you are correct in the model, as I found these lines:

 

2013-05-14 7:44:08.000 PM kernel[0]: E7 report: [73 03 0a]
2013-05-14 7:44:08.000 PM kernel[0]: E7: { 0x73, 0x03, 0x0a } E6: { 0x00, 0x00, 0x64 }
2013-05-14 7:44:08.000 PM kernel[0]: Discovered touchpad version: 0x7331
2013-05-14 7:44:08.000 PM kernel[0]: ALPS Device? no
2013-05-14 7:44:08.000 PM kernel[0]: ApplePS2ALPSGlidePoint::probe leaving.
 

If you think there is a possibility to get this touchpad working better, that is fantastic. As it stands right now, it is usable, but either 2 finger scrolling or edge scrolling would be great!

 

Thanks

So, some questions:

- What version of OSX are you running?

 

- Run the following 2 commands in a terminal:

find /System/Library/Extensions -name '*PS2*'

find /Extra/Extensions -name '*PS2*'

And paste the output..This is to make sure that no other PS2 kexts are there including the AppleACPIPS2Nub and ApplePS2Controller which should not exist anywhere...sometimes those kexts get left over either in /E/E or in /S/L/E/myHack.kext/PlugIns

- Did it not work at all? Or just no side-scrolling or whatever?

 

Also, I have noticed at other times that sometimes the kexts don't get refreshed properly until after a couple reboots...but it may have been my own fault...should be OK as long as you use myHack and run a quick fix or just regenerate the kext cache

 

I'm running 10.8.3. I had an older VoodooPS2Controller lurking around in /S/L/E/myHack.kext, but i purged it and it still does not work. Not working meaning no reaction from either trackpad or trackpad at all.

 

Here's what i found in system.log after loading the debug version:

Yeah, I will definitely see what I can do...hopefully just a few days...

It would be awesome if we could get this to work...

 

Those log lines are exactly what I get with my touchpad...everything looks good there from what I can tell. Even the command mode response (the line with ApplePS2ALPSGlidePoint EC Report) is the same which means it is definitely the exact same model.

 

Could you open up a terminal once you login with the debug version (i.e. use a USB mouse if you have to) and run 'tail -f /var/log/system.log' and then try to make some movements on the touchpad and see if anything shows up there?

Strange! I get nothing, just debug messages from the keyboard when I stroke a key. The touchpad is just numb.

 

Hmm. Do you happen to have another mouse plugged in...I just remembered that I think the VoodooPS2Daemon will disable the touchpad if another mouse is plugged in.

 

If that does not help, could you attach the whole system.log file from bootup to login?

Nope. Normally i have a magic trackpad connected, but I tried booting up while having it switched off - still nothing. Thanks for looking into this...!

OK everybody, I did a major rework of the driver to be as close to the Linux v3.9 driver as possible. It supports a lot more models now, though it is still lacking protocol v1/v2 support. I need to figure out how exactly to process the info from those.

 

olvidalo, it would be great if you could try out this new version and see if it works for you.

 

driedger, try out this new version and see if it works, though I am afraid it may still not work. I did not see your signature listed in the v3.9 driver. However, there is a chance that if your command mode response matches some things it checks for it may work...

 

Let me know what you guys find, it is working for me.
