+
+ If you say N, all options in this submenu will be skipped and disabled.

+config HID
+ tristate "Generic HID 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 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_BATTERY_STRENGTH
+ bool
+ depends on HID && POWER_SUPPLY && HID = POWER_SUPPLY
+ default n
+
+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.

+ * There exists an official driver on the manufacturer's website, which
+ * wasn't submitted to the kernel, for some reason. The official driver
+ * doesn't seem to support extra features of some tablets, like wheels.
+ *
+ * It shows that the feature report ID 2 could be used to control any waltop
+ * tablet input mode, switching it between "default", "tablet" and "ink".
+ *
+ * This driver only uses "default" mode for all the supported tablets. This
+ * mode tries to be HID-compatible (not very successfully), but cripples the
+ * resolution of some tablets.
+ *
+ * The "tablet" mode uses some proprietary, yet decipherable protocol, which
+ * represents the correct resolution, but is possibly HID-incompatible (i.e.
+ * indescribable by a report descriptor).
+ *
+ * The purpose of the "ink" mode is unknown.
+ *
+ * The feature reports needed for switching to each mode are these:
+ *
+ * 02 16 00 default
+ * 02 16 01 tablet
+ * 02 16 02 ink
