Confusion with i8042prt and PS2 mouse and keyboard

  1. Hi all,

    I would appreciate some guidance here: I was examining
    the driver list of a laptop and realized \Device\PointerClass
    and \Device\KeyboardClass devices are not attached to
    any device object managed by the i8042prt driver...
    so I thought, hm... must be because they are not
    PS2 devices. Then I moved on to another laptop that has
    no PS2 ports either (only USB)
    and saw that its \Device\PointerClass does attach on
    top of i8042prt... I am confused.

    Shouldn't all pointing device rely on i8042prt to
    receive data? If not, how does it work? How do
    I go about finding out what device object/driver
    object it gets data from?

    Thanks, any information appreciated.
