Tell me about it.
Everything I read, days and days now, i tried. none of it worked.
I am pretty sure it is a 2.6 kernel issue since 2.4 kernel works just fine.
I don't consider de-activating wheel and any other features as a solution
I am not flaming, but does anyone know if there is actually going to be
a solution for this? I hate to say this, but it Just Works(TM) in
Windows XP and older versions of Linux. What is it about the 2.6 kernel
that is causing this issue - does anyone know?
This old html depicts the exact same problem I have.
Do you know how he did to fix it?
Part of message pasted below:
I've found a fix for a problem I was having with the combination
of my Logitech trackball's scrollwheel and my KVM switch. My scroll
wheel would work until I switched away from my Linux desktop; after
switching back, the evbug module reported no events when turning the
According to Belkin, this is because my KVM switch does not
support the Logitech protocol, only the MS Intellimouse one. I
noticed that WinXP had no such problems, so I commented out the section
in psmouse_extensions() that detected Logitech mice. Now my trackball
is detected as a "ImPS/2 Generic Wheel Mouse" and the scroll wheel
It would be good to have a parameter that would allow me to force
this mouse to use the ImPS/2 protocol rather than the logitech PS2++; I
probably won't be the last person to have this kind of problem (which
I didn't have with 2.4).
The following patch makes that parameter: psmouse_imps2. Will you
consider it applying it, or something like it?
