In linux kernel since version 2.6.24 (release Date: 2008-01-24)  
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.
