/dev/input

Files I've encountered under /dev/input or might be present include
event0 … event16 Event queues.
mice Unified mouse
mouse0 … mouse2
jsN Joysticks
In addition there were also two directories: by-id and by-path.
Some (all?) of the file names found in /dev/input are also present under /sys/class/input.

Capturing mouse movements

/dev/input/mouse3 (why mouse3?) emits data when the mouse is moved: 
sudo cat /dev/input/mouse3

TODO

sudo gpm -m /dev/input/mice -t help
mev is a program to report mouse events:
