Clarification about that MatchProduct keyword:
Hal and udev differ slightly in the way they identify hardware devices
(is anyone surprised?).
When I run 'lshal' to display all my hardware, I see this about the mouse:
info.product = 'ImExPS/2 Logitech Explorer Mouse'
Now for the confusion. When I run 'udevadm info --export-db" I see:
E: NAME="ImExPS/2 Logitech Explorer Mouse"
Note that MatchProduct in the xorg.conf file really wants the udev NAME,
*not* the udev PRODUCT.
I suppose the MatchProduct keyword was selected back in the day when
hal was still the boss instead of a has-been. "MatchName" would be much
less confusing than "MatchProduct". But don't hold your breath waiting
for it to change.
