I _think_ I see a little initialization data pass down
the
line, to the mouse, when I first power up the device, but
my o'scope isn't a memory type, so it might just be power
up noise.
If you repeatedly pulse the MCLR pin you can repeat the reset
sequence often enough to view it on the scope. If it is power
up noise it may be confusing the mouse enough to stop it working.
