---help---
A human interface device (HID) is a type of computer device that
interacts directly with and takes input from humans. The term "HID"
most commonly used to refer to the USB-HID specification, but other
devices (such as, but not strictly limited to, Bluetooth) are
designed using HID specification (this involves certain keyboards,
mice, tablets, etc). This option compiles into kernel the generic
HID layer code (parser, usages, etc.), which can then be used by
transport-specific HID implementation (like USB or Bluetooth).
For docs and specs, see http://www.usb.org/developers/hidpage/
If unsure, say Y
config HID_DEBUG
bool "HID debugging support"
depends on HID
---help---
This option lets the HID layer output diagnostics about its internal
state, resolve HID usages, dump HID fields, etc. Individual HID drivers
use this debugging facility to output information about individual HID
devices, etc.
This feature is useful for those who are either debugging the HID parser
or any HID hardware device.
If unsure, say N
