    With the kernel input layer, there are three components to the mouse
    driver now. One is 'psmouse', which you already have loaded. Another
    is 'input', which is autoloaded. The third is the frontend,
    'mousedev', which takes mouse data and produces an emulated PS/2
    Intellimouse on /dev/input/mice - and optionally on /dev/psaux as well,
    for backward compatibility.

    Note that 'mousedev' is not strictly needed - if your applications can
    deal with the 'event interface' instead, you can just load the 'evdev'
    module and use /dev/input/event0 et al. as an alternate "front-end
    driver" for mouse packet output. But normally you just want 'mousedev'
    and /dev/input/mice.
