Any news here?

I think this is what you hit too, Andres?


Interesting part from the Andres' email follows:

I have an Apple Mighty Mouse. This is how it looks with 'cat
/proc/bus/input/devices'

I: Bus=0005 Vendor=05ac Product=030c Version=0200
N: Name="Mighty Mouse"

And the trackball on it has it x axis inverted.

Ive searched about this problem and found a Linux kernel mailing list
conversation where this error maybe had raised. A guy but a similar
mouse (also a mightymouse), but different ID (0x1000 instead of 0x030c),
was told to invert the x axis in order to have his 0x1000 mighty mouse
working with the wrong ID: 0x030c instead of adding a while new device.
Probably, inverting the trackball for the rest of us with the right id.

I will quote the mailing list post to you:
