Take a look at a tool I've made as a part of my current solution to hotplug my
Wacom tablet . There's a program included that can record data directly
from the eventX kernel device (if the kernel module is used you can do this
at the same time as you see what you do) and later play this back through the
same device with the right pacing.
Could this help you in your quest?
