Great, speed is much better; totally useable for me. Your PS2 controller v4.0.0 is now spot on and perfect for all my Latitude E Series.

 

Thanks again.

 

Excellent news :)

Thank you for all your time testing.

 

You can consider RC4 the final release for now (till I update the opening post tonight).

Sorry, I did a major mistake in test 3 regarding V8 hardware. Deleted the attachment before it causes KPs.   V8 test 4: (same as test 3, but corrected).. - V8 byte check, fix flags, mask, and maxes

I just found out that I had an embarrassingly major mistake in the driver that caused it to clash with the base driver  Fixed that and performance seems significantly and even tangibly improved!! Th

Yeah, there was just ever singletouch with it on OS X without preference by the rehabman's(your kext make the preference work). And RC4 didn't make it work even buttons or scrolling, just like not having driver with it. Thanks for your doing. Hoping the newer version for mine. :-P

Try this:

 

Dolphin alpha 1:

- Ported new V5 init code.

 

THIS COULD CAUSE A KERNEL PANIC. 

Run it from a Clover USB stick.

 

Check dmesg and console messages and post here.

Dell e7440. Rc4, trackpad movement choppy. You can't move cursor across the whole touchpad, because it stops by itself. Lifting finger helps and you can move again. Gestures work great. Also scrolling is laggy, not smooth. In fact last Rehabman version is better for me on e7440 but lacks gestures support. Any suggestions? Sierra 10.12.1

Dr.Hurt, what the information do you want  from console, where?

It seems that there is nothing about alps touchpad in console.

 

Nothing in console because the touchpad failed to initialize.

 

Dolphin V2 doesn't even work properly with the default driver on Linux.

I did however find a user-patch and ported it to this driver for you to test.

OK, it doesn't work but it seems something different in the dmesg.

This is the new dmesg.
