OK.
From an actual root user go to the '/dev/input' drawer and:
cat < mouse0
AND:
cat < mice
...and in each see if mouse movement presents garbage on the terminal window.
Ctrl-C should quit the test(s).
The redirection is implicit normally but I have known when attacking the HW normal rules sometimes do not apply so one has to be explicit.
One of the 'events' does the same but it was ages ago and I can't remember which one it is.

Hi drew77...
I am pretty sure on a personal system you need root access to mess with HW devices.
But this was 10+ years ago when I hammered the HW via its device structure on a Linux tool.
Do you not have root access at all as an admin?
