# HID driver configuration

menu "HID support"
depends on INPUT
config HID
tristate "HID bus support"
depends on INPUT
default y
---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 adds the HID bus to the kernel,
together with generic HID layer code. The HID devices are added and
removed from the HID bus by the transport-layer drivers, such as
usbhid (USB_HID) and hidp (BT_HIDP).
For docs and specs, see http://www.usb.org/developers/hidpage/
If unsure, say Y.
if HID
config HID_BATTERY_STRENGTH
bool "Battery level reporting for HID devices"
depends on HID
select POWER_SUPPLY
default n
---help---
This option adds support of reporting battery strength (for HID devices
that support this feature) through power_supply class so that userspace
tools, such as upower, can display it.
config HIDRAW
bool "/dev/hidraw raw HID device support"
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.
config UHID
tristate "User-space I/O driver support for HID subsystem"
depends on HID
default n
---help---
Say Y here if you want to provide HID I/O Drivers from user-space.
This allows to write I/O drivers in user-space and feed the data from
the device into the kernel. The kernel parses the HID reports, loads the
corresponding HID Device Driver or provides input devices on top of your
user-space device.
This driver cannot be used to parse HID-reports in user-space and write
special HID-drivers. You should use hidraw for that.
Instead, this driver allows to write the transport-layer driver in
user-space like USB-HID and Bluetooth-HID do in kernel-space.
If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called uhid.
config HID_GENERIC
tristate "Generic HID driver"
depends on HID
default HID
---help---
Support for generic devices on the HID bus. This includes most
keyboards and mice, joysticks, tablets and digitizers.
To compile this driver as a module, choose M here: the module
will be called hid-generic.
If unsure, say Y.
menu "Special HID drivers"
depends on HID
config HID_A4TECH
tristate "A4 tech mice"

select INPUT_FF_MEMLESS
---help---
Say Y here if you want to enable force feedback support for ACRUX
game controllers.
config HID_APPLE
tristate "Apple {i,Power,Mac}Books"
depends on HID
default !EXPERT
---help---
Support for some Apple devices which less or more break
HID specification.
Say Y here if you want support for keyboards of Apple iBooks, PowerBooks,
MacBooks, MacBook Pros and Apple Aluminum.
config HID_APPLEIR
tristate "Apple infrared receiver"
depends on (USB_HID)
---help---
Support for Apple infrared remote control. All the Apple computers from
2005 onwards include such a port, except the unibody Macbook (2009),
and Mac Pros. This receiver is also used in the Apple TV set-top box
prior to the 2010 model.
Say Y here if you want support for Apple infrared remote control.

for events and handle data streams. Each sensor driver can format
data and present to user mode using input or IIO interface.
config HID_SENSOR_CUSTOM_SENSOR
tristate "HID Sensors hub custom sensor support"
depends on HID_SENSOR_HUB
default n
---help---
HID Sensor hub specification allows definition of some custom and
generic sensors. Unlike other HID sensors, they can't be exported
via Linux IIO because of custom fields. This is up to the manufacturer
to decide how to interpret these special sensor ids and process in
the user space. Currently some manufacturers are using these ids for
sensor calibration and debugging other sensors. Manufacturers
should't use these special custom sensor ids to export any of the
standard sensors.

* Roccat Kone is a gamer mouse which consists of a mouse part and a keyboard
* part. The keyboard part enables the mouse to execute stored macros with mixed
* key- and button-events.
*
* TODO implement on-the-fly polling-rate change
* The windows driver has the ability to change the polling rate of the
* device on the press of a mousebutton.
* Is it possible to remove and reinstall the urb in raw-event- or any
* other handler, or to defer this action to be executed somewhere else?
*
* TODO is it possible to overwrite group for sysfs attributes via udev?
