OK, we can stop worrying about the kernel configuration for the moment.
Now I would be interested in some details about your misplaced event
devices; please show me the output of:
stat /dev/event7
Also, let's check what udev is doing, with this command:
udevadm test /class/input/input7/event7
This will produce a lot of output; please make it available on
http://debian.pastebin.com and post the link here.
