[SOLVED] Mouse buttons stopped working

Question

I have a Logitech Marble Mouse (connected via a USB to PS/2 adapter).  It has no scrollwheel, so I set up the small "extra" pair of buttons to toggle "scroll mode" in certain applications (like Firefox & Chrome).  When activated, moving the trackball scrolls the page up/down/left/right instead of moving the pointer.
It's been working fine for months, but a week or so ago, the scroll buttons suddenly stopped working.  The settings are contained at the very bottom of the file /etc/X11/xorg.conf.d/10-evdev.org, and the only other file in that directory matches "ThinkPad HDAPS acceleromer data", so shouldn't affect the mouse settings.
(The buttons that don't work are "B" and "C", which both activated scroll mode:)

I've tried playing around with the button-mapping, even jumbling 4 5 6 7 to 5 4 7 6 (which, I thought, should invert the movement of the pointer), but none of this has any effect.  I've checked /etc/X11/xorg.conf, and I don't seem to have any mouse-related settings there... and I've read the wiki, but I can't see what I'm doing wrong!
Can anyone help? :-)

Answer 1

I don't think, that evdev has something to do with the xf86-input-mouse. But I belive, this is a real issue, because my good old configuration stopped working (buttons aren't customized) today as well. Looks like the reason is hidden somewhere in yesterdays pacman -Syu .
