menuconfig HID_SUPPORT
bool "HID bus support"
default y
depends on INPUT
help
This option adds core support for human interface device (HID).
You will also need drivers from the following menu to make use of it.
if HID_SUPPORT
config HID
tristate "HID bus core support"
default y
depends on INPUT
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 https://www.usb.org/developers/hidpage/
If unsure, say Y.
if HID
config HID_BATTERY_STRENGTH
bool "Battery level reporting for HID devices"
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"
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 Uninterruptible 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"
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"
default HID
