Apologies for replying to my own post. I found the solution and it might
benefit others who encounter this issue.

What I forgot to mention is that I'm using a laptop with a synaptics
touchpad and a usb mouse. The configs on F8 & F9 are the same but after
comparing the log files I noticed that there is a difference in what X
decides about the touchpad reporting core events. 

On F8 it says "(**) <default pointer>: always reports core events"
On F9 it says "(**) <default pointer>: doesn't report core events"

On F9 in /etc/X11/xorg.conf changing this line:
InputDevice    "Synaptics" "CorePointer"
to
InputDevice    "Synaptics" "AlwaysCore"

will make the usb mouse work again.
