Fujitsu scroll wheel does not function correctly

Hy,

I have a Fujitsu s762 that has a scroll whell or scroll pad or whatever, a little circular touchpad that scrolls up/down on ms windows when you move your finger circularry on it.
This image shows the device: http://www.eclipsecat.com/sites/default … nt_fps.jpg

So this thing is detected by the psmosue driver as a separate event device named "DualPoint Stick" and it sends BTN_MIDDLE events when you try to scroll up, and nothing when down.

Anyone has such device, or any idea how to make it work?

Thanks!

Re: Fujitsu scroll wheel does not function correctly

Well, I had to fix it at driver level...

Here is a patched psmouse driver if anyone is interested:

Re: Fujitsu scroll wheel does not function correctly

Hi u-foka,

I have a S761 with the same scroll wheel. Now I found your solution, but If I try to compile I get errors.

Do you have an Idea?

Re: Fujitsu scroll wheel does not function correctly

Hy!

The error in your output shows some problem on the synaptics part of the psmouse driver which I never touched, my driver is based on the current linux 3.9 git tree and has only about 15 lines changed in the alps.c and .h files. Maybe your linux-headers package is old.

So first questions are:
Do you have an up2date system? What is your kernel version?

Hi Tamás,

>Do you have an up2date system? What is your kernel version?

I use the kernel version 3.2 with the Ubuntu 12.04. I do not really want to update the kernel. Do you see a possibility to implement your patch in the linux 3.2?

Thanks,

Re: Fujitsu scroll wheel does not function correctly

Hmm, I can give you the patch, and it should apply fine on linux 3.2, also if I will have some time in the weekend, I can make a ppa for ubuntu 12.04 smile

Re: Fujitsu scroll wheel does not function correctly

Well, there are much more changes than I expected between the two version, so backporting the patch can take a little more time.. I'l tell you when it's ready!

Re: Fujitsu scroll wheel does not function correctly

Hi Tamás,

to compile and install worked just fine. But the scroll wheel doesn't work.

How can I test the scroll wheel?

Thanks,
