Hi! I looked at one of the recordings that was sent, and I just wanted
to clarify that the version you probably should be using to record
everything is ps2emu v0.1.2. The one that's in the master branch right
now is not entirely stable, and it's giving us a couple of problems
replaying the events on our machine. You can find the stable release
here:

It is not enough. If do not want to recompile full kernel, but

psmouse.ko I think that the easiest way is to change this 
define

 #define psmouse_dbg

in file drivers/input/mouse/psmouse.h to call dev_warn instead 
dev_dbg.
And then just compile psmouse.ko and reload it.

Thanks, that seemed to do the trick.  This is what I get from 
dmesg now:

Ok, your ALPS touchpad is identified as:

{ { 0x22, 0x02, 0x14 }, 0x00, { ALPS_PROTO_V2, 0xff, 0xff, 
ALPS_PASS | ALPS_DUALPOINT } },      /* Dell Latitude D600 */

You mentioned that commit 92bac83d introduced your problem:

========================================
commit 92bac83dd79e60e65c475222e41a992a70434beb
Author: Hans de Goede [off-list ref]
Date:   Sun Apr 12 15:42:35 2015 -0700

    Input: alps - non interleaved V2 dualpoint has separate stick 
button bits
========================================

Hans, can you look at this problem as it is clearly problem with
protocol V2?

Douglas, can you please make a recording of your touchpad/trackstick
with ps2emu-record?
Download it from https://github.com/Lyude/ps2emu , compile it and run
it as root:
- once the touchpad gets re-initialized:
- click once, wait a few seconds
- click twice, wait a few seconds
- click three times, wait few seconds
- use the touchpad a bit, wait a few secs
- use the trackstick (and its buttons) a bit
- Ctrl-C

And send us the resulting file ps2emu_record.txt that will be created
in the current directory.

Can you also confirm that your laptop has a trackstick as seen on
http://www.newegg.com/Product/Product.aspx?Item=N82E16834114551 ?

Cheers,
Benjamin

PS: I am not sure we tested ps2emu-record on an Alps touchpad before,
apologies if there are some hiccups...
