1 second at 1MHz.

Initialize a ps2 mouse, configure it; the mouse then reports movement data.

    - host resets device, waits for reset to complete
    - host sets sample rate to 200, 100, 80 - this activates reporting scroll wheel data is available
    - host sets device to maximum sample rate: 200; resolution=1: 2 count/mm; 1:1 scaling, stream mode
    - host gets device id, enable data reporting
    - after a delay, the mouse is moved, and reports it's changing location, in sequences of 4 bytes:
        - flags, x movement, y movement, z (scroll wheel) movement.
        - the sample data does not include any button presses or scroll wheel movement

Thanks for this capture!
I see that this is the 4-byte "microsoft mouse" protocol which includes the scrollwheel.

Please rename the file "ps2_microsoft_mouse_initialize_and_move.sr" and move to the ps2/mouse directory
