No, it all looks normal.  As a check you could compare this with the
file contents while the mouse is still operating normally.  About the
only difference should be the "hcca frame" line, which changes
constantly.

I guess the next test should be to wait for the mouse to stop working,
unplug the mouse, and then see once again what these files contain.
