USB HID is a general class for USB devices which includes keyboards, mice and joysticks (amongst other things): http://en.wikipedia.org/wiki/USB_human_interface_device_class So just because something is a USB HID, does not mean that the events are ignored by default by the OS. For example, events from switch interfaces that emulate mice are not ignored by default on modern Linux systems. Xinput2 will help this problem by allowing us to put these switch devices into a 'floating slave' mode which will allow apps to register for events from the specific device. When a device is in this mode, events are not sent to any of the pointers - yes, there can be more than one pointer with xinput2! I hope this clears things up a bit :-).
