Genius Ergo 525 Support

[euphi2]

I have a Genius Ergo 525 mouse with a "tilt wheel" (vertical and horizontal scrolling) and 4 extra buttons.

I hoped the extra buttons are normal mouse buttons, but they exactly do what's written on the packing: Lower/Raise volume and change song -- they send the default multimedia keycodes - XF86Audio.... Ok.. However, they work.. so thats ok.
(With google, I haven't found anything except this: http://www.linuxquestions.org/questions/showthread.php?p=2174128 (question only, no answer).

What is not ok, is the horizontal scrolling - no Events can be seen with xev - and there is also no data in /dev/input/mouse0.

So, my questions:

1. Has anybody got the horizontal scrolling running?

2. As there are no data sent to the /dev/input/mouse0 device: How does the kernel modify/forward the received data from the mouse to the device-node?

3. What happens with unknown keycodes: Is it possible that the horizontal scrolling is realized as KEYBOARD event (like the extra buttons) - but the key code is not forwarded to X applications, because it is unknown?

3a) Who is responsible for analyzing received keyboard codes? Kernel? X.Org? W


I'm quite good in C programming, so I don't fear to play around in some kernel or X.org sources, but I have no experience with kernel drivers yet.

Hello,
I met the same pb with an ergo 520.
I couldn't have the horizontal scroll wheel
I've added a rule in uvdev (in /etc/udev/rules.d/10-local.rules):

Of course the same applies to the 520. I have both 520 and 525 they behave exactly same.
