[dix] cannot find pointer to pair with. This is a bug

Using USB keyboard/mouse

Using the same HW/kernel/X conf, this problem does not occur with Xorg 7.3 system w/ xorg-server 1.4 (or previous Xorg versions ie. Debian Etch w/ Xorg 7.1). Have also tried another kbd/mouse device (ThinkPad USB kbd w/ integrated trackpoint/touchpad - which also works with previous Xorg versions) which also fails similar.

Full Xorg.0.log attached.
