OK... This is amazing.

Installed Debug version first to test it out. Found that touch pad worked, but was almost unusable. Cursor jumping around, needing to press very hard on touchpad for it to detect movement... but 2 finger scroll worked! 

I went into the prefpane, and the stock trackpad prefpane detected the trackpad this time, and allowed me to make some speed adjustments. Previously, the synaptics prefpane would crash out immediately, but with this new driver it loads! It appears that although each option in the prefpane showed a value, there was actually no value loaded. So by simply changing the values, or checking a box and then unchecking it again, I was able to tweak settings to get everything working fairly well.

 

Finger Z value adjustment made the biggest difference. I was able to set the sensitivity, and get tap to click working. 

Scrolling tab adjustments got side scrolling working, but its a bit unreliable still.. but definitely usable!

Multi Finger Scrolling works, both vertically and horizontally.

 

With this update, the track point is completely unusable. Movements are inverted, and completely erratic. Not a deal breaker though as I dont like to use it as much as I used to with my old thinkpad and tecra.

 

 

Below is the model detected by the debug version of the driver:

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

Just added support for v1/v2 models. Not sure if it works correctly, but hopefully it works somewhat. At least now it is a full port for all models of ALPS touchpads. Adding more support in the future should be easier since it will be minor changes to track the linux driver.

 

I just got a new laptop today so I don't know how much more debugging I will be able to do with this driver anymore on my own. At least the source is all open so anyone can help out and I can still at least try to make changes.

 

My next step right now is to get this merged in with ReHabMan's code so it can share the same fixes he makes for other parts of the driver (keyboard, mouse, and other shared stuff)

wow amazing, great work..... need to test it on old "D" series... so do you think this can replace some of the older buggier kexts in EDP and if so witch ones or will it replace all the alps options? would be nice to just have one working option then a bunch of different options.

which download do i use to test on an old "D"series? i tried your version 4 but trackpad did not respond.

 

V4 is the latest so that should be it. Would you be able to try the debug version and post the system.log from bootup to login and include some touchpad touches? I know that there are some settings I have defaulted that may not work so well with the other versions...like the acceleration multiplier.

OK, so it is getting detected as an ALPS device and detecting the correct version which is good. However, I need to see more logging, right at the end of what you pasted is the beginning of the hardware initialization.
