Well, usb_hid does not correspond to one kind of device. In case of
KeyboardDevice it is a keyboard, in case of MouseDevice it is a mouse
and gets published and used as such. The ioctls received by the
input_server are device type specific. In case of mice there is MS_READ
in case of keyboards it is KB_READ and in case of joysticks it seems to
be B_JOYSTICK_* stuff. I suppose this isn't really setup to be handled
by input_server but a specialized add-on and BJoystick? I really don't
know as I don't know the input_server side. In any case the joystick
shouldn't be a used as a mouse IMHO and should not publish itself as
such to the system. If we implement joystick support through
input_server then as you mentioned a corresponding add-on could however
convert that joystick data to mouse movement. Input from someone having
a more detailed picture of how we're going to implement joystick
support in general would be helpful here.
