In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
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 Uninterruptible Power Supplies.

This module supports these devices separately using a separate
event interface on /dev/usb/hiddevX (char 180:96 to 180:111).

If unsure, say Y.
