I'd suggest running the evtest.c program on event9 to see what it is
sending out. And then if it's reporting things properly, make sure xorg
is reading from it in order to get the messages that way.
I've attached an older version of evtest.c, you might be able to find a
newer one on the internet somewhere.
Hope this helps,
