Mouse wheel does not work with kernel 2.6.x

[Joerg Johannes <liste_joerg@gmx.de>]

Hi everybody

This is a bit strange to me, and I don't exactly know how to track the
problem down. Here are the symptoms:

I have a logitech USB mouse which works great using 2.4 kernels. With
exactly the same setup in X, the same mouse attached to the same
computer works still, but only the three buttons: scrolling the wheel
doesn't do anything, pressing it works as "paste" like it should.
Obviously it can't be the X configuration which is faulty, because it
still works when I boot back to 2.4. Also the kernel configuration
should be OK, because otherwise the mouse wouldn't work at all.

snippets from some (maybe) interesting files:
