	depends on HID

	---help---

	Say Y here if you want to support HID devices (from the USB

	specification standpoint) that aren't strictly user interface

	devices, like monitor controls and Uninterruptable Power Supplies.



	This module supports these devices separately using a separate

	event interface on /dev/hidraw.



	There is also a /dev/hiddev configuration option in the USB HID

	configuration menu. In comparison to hiddev, this device does not process

	the hid events at all (no parsing, no lookups). This lets applications

	to work on raw hid events when they want to, and avoid using transport-specific

	userspace libhid/libusb libraries.



	If unsure, say Y.
