ROCCAT mouse doesn't work ("failed to attach handler kbd")

[Max_JD]

Hey,

I'm kind of new to Gentoo (installed it some years ago, but used Ubuntu most of the time) but I wanted to give it a try again these days I currently use kernel 3.12.13, basically everything is working and I eventually got the nvidia drivers running.

But I'm stuck with the "Roccat Savu" mouse I want to use. I compiled the related kernel module (tried to compile in, and compile as module, both are same) and get the following errors, when booting and when starting X:

dmesg output
/var/log/Xorg.0.log

I think the interesting parts are these:

From dmesg:

I know and studied the first linked page, but it contained nothing I found useful or helped me in this situation (the page was actually linked in my first post if you look carefully )

The official forum of the ROCCAT kmod driver developer also contained nothing that helped me any futher (althougth it might be possible that I overlook something, as I didn't read every single post). I thought, that the problem was more likely to be related to the Linux distribution, as the mouse works perfectly for me under Ubuntu. Therefore, I choose this forum over the mentioned one. But I will try to ask there, if I don't find a solution over the next days...

Thanks anyway

I finally sorted out my problem, but I can not really tell where it came from exactly. The idea was to start from a kernel config, where the mouse works (in my case I used the gentoo-minimal Install CD config). After the mouse worked I had to sort out, why the nvidia drivers were so laggy... -.-

The problem is basically that I always changed so many kernel config settings, that I can hardly tell where all these problems came from. I will just post my working kernel config:

working kernel config

If anyone wants to "spot the difference" I would be happy to know where exactly the behavior origins I think the only module I ever changed on HID devices themself is the Battery status module (whicht I don't compile anymore).

The solution to this problem is the way described above.

Edit:
Oh. and much thanks go to Dominique as you can see here: https://sourceforge.net/p/roccat/discussion/989581/thread/ae60665c/

I received a kernel message in dmesg similar to this for a wireless keyboard, where the keyboard worked but the trackpad didn't:
