---help---
Say Y here if you want full HID support to connect USB keyboards,
mice, joysticks, graphic tablets, or any other HID based devices
to your computer via USB, as well as Uninterruptible Power Supply
(UPS) and monitor control devices.
You can't use this driver and the HIDBP (Boot Protocol) keyboard
and mouse drivers at the same time. More information is available:
<file:Documentation/input/input.txt>.
If unsure, say Y.
To compile this driver as a module, choose M here: the
module will be called usbhid.

* USB ATI Remote support
*
* Version 2.2.0 Copyright (c) 2004 Torrey Hoffman <thoffman@arnor.net>
* Version 2.1.1 Copyright (c) 2002 Vladimir Dergachev
*
* This 2.2.0 version is a rewrite / cleanup of the 2.1.1 driver, including
* porting to the 2.6 kernel interfaces, along with other modification
* to better match the style of the existing usb/input drivers. However, the
* protocol and hardware handling is essentially unchanged from 2.1.1.
*
* The 2.1.1 driver was derived from the usbati_remote and usbkbd drivers by
* Vojtech Pavlik.
*
* Changes:
*
* Feb 2004: Torrey Hoffman <thoffman@arnor.net>
* Version 2.2.0
* Jun 2004: Torrey Hoffman <thoffman@arnor.net>
* Version 2.2.1
* Added key repeat support contributed by:
* Vincent Vanackere <vanackere@lif.univ-mrs.fr>
* Added support for the "Lola" remote contributed by:
* Seth Cohn <sethcohn@yahoo.com>

* Hardware & software notes
*
* These remote controls are distributed by ATI as part of their
* "All-In-Wonder" video card packages. The receiver self-identifies as a
* "USB Receiver" with manufacturer "X10 Wireless Technology Inc".
*
* The "Lola" remote is available from X10. See:
* http://www.x10.com/products/lola_sg1.htm
* The Lola is similar to the ATI remote but has no mouse support, and slightly
* different keys.
*
* It is possible to use multiple receivers and remotes on multiple computers
* simultaneously by configuring them to use specific channels.
*
* The RF protocol used by the remote supports 16 distinct channels, 1 to 16.
* Actually, it may even support more, at least in some revisions of the
* hardware.
*
* Each remote can be configured to transmit on one channel as follows:
* - Press and hold the "hand icon" button.
* - When the red LED starts to blink, let go of the "hand icon" button.
* - When it stops blinking, input the channel code as two digits, from 01
* to 16, and press the hand icon again.
*
* The timing can be a little tricky. Try loading the module with debug=1
* to have the kernel print out messages about the remote control number
* and mask. Note: debugging prints remote numbers as zero-based hexadecimal.
*
* The driver has a "channel_mask" parameter. This bitmask specifies which
* channels will be ignored by the module. To mask out channels, just add
* all the 2^channel_number values together.
*
* For instance, set channel_mask = 2^4 = 16 (binary 10000) to make ati_remote
* ignore signals coming from remote controls transmitting on channel 4, but
* accept all other channels.
*
* Or, set channel_mask = 65533, (0xFFFD), and all channels except 1 will be
* ignored.
*
* The default is 0 (respond to all channels). Bit 0 and bits 17-32 of this
* parameter are unused.

*
* It has meant that I've been able to correct my interpretation of the

*
* CC -- 2003/9/29
*
* History
* 1.0 & 1.1 2003 (CC) vojtech@suse.cz
* Original version for 2.4.x kernels
*
* 1.2 02/03/2005 (HCE) hc@mivu.no
* Complete rewrite to support Linux 2.6.10, thanks to mtouchusb.c for hints.
* Unfortunately no calibration support at this time.
*
* 1.2.1 09/03/2005 (HCE) hc@mivu.no
* Code cleanup and adjusting syntax to start matching kernel standards
*
* 1.2.2 10/05/2006 (MJA) massad@gmail.com
* Flag for detecting if the screen was being touch was incorrectly
* inverted, so no touch events were being detected.

*
* History
*
* 0.3 & 0.4 2002 (TEJ) tejohnson@yahoo.com
* Updated to 2.4.18, then 2.4.19
* Old version still relied on stealing a minor
*
* 0.5 02/26/2004 (TEJ) tejohnson@yahoo.com
* Complete rewrite using Linux Input in 2.6.3
* Unfortunately no calibration support at this time
*
* 1.4 04/25/2004 (TEJ) tejohnson@yahoo.com
* Changed reset from standard USB dev reset to vendor reset
* Changed data sent to host from compensated to raw coordinates
* Eliminated vendor/product module params
* Performed multiple successful tests with an EXII-5010UC
*
* 1.5 02/27/2005 ddstreet@ieee.org
* Added module parameter to select raw or hw-calibrated coordinate reporting

/*
* A driver for the Griffin Technology, Inc. "PowerMate" USB controller dial.
*
* v1.1, (c)2002 William R Sowerbutts <will@sowerbutts.com>
*
* This device is a anodised aluminium knob which connects over USB. It can measure
* clockwise and anticlockwise rotation. The dial also acts as a pushbutton with
* a spring for automatic release. The base contains a pair of LEDs which illuminate
* the translucent base. It rotates without limit and reports its relative rotation
* back to the host when polled by the USB controller.
*
* Testing with the knob I have has shown that it measures approximately 94 "clicks"
* for one full rotation. Testing with my High Speed Rotation Actuator (ok, it was
* a variable speed cordless electric drill) has shown that the device can measure
* speeds of up to 7 clicks either clockwise or anticlockwise between pollings from
* the host. If it counts more than 7 clicks before it is polled, it will wrap back
* to zero and start counting again. This was at quite high speed, however, almost
* certainly faster than the human hand could turn it. Griffin say that it loses a
* pulse or two on a direction change; the granularity is so fine that I never
* noticed this in practice.
*
* The device's microcontroller can be programmed to set the LED to either a constant
* intensity, or to a rhythmic pulsing. Several patterns and speeds are available.
*
* Griffin were very happy to provide documentation and free hardware for development.
*
* Some userspace tools are available on the web: http://sowerbutts.com/powermate/

*
* This driver is based on:
* - information from http://euc.jp/periphs/xbox-controller.ja.html
* - the iForce driver drivers/char/joystick/iforce.c
* - the skeleton-driver drivers/usb/usb-skeleton.c
*
* Thanks to:
* - ITO Takayuki for providing essential xpad information on his website
* - Vojtech Pavlik - iforce driver / input subsystem
* - Greg Kroah-Hartman - usb-skeleton driver
* - XBOX Linux project - extra USB id's
*
* TODO:
* - fine tune axes (especially trigger axes)
* - fix "analog" buttons (reported as digital now)
* - get rumble working
* - need USB IDs for other dance pads
*
* History:
*
* 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"
*
* 2002-07-02 - 0.0.2 : basic working version
* - all axes and 9 of the 10 buttons work (german InterAct device)
* - the black button does not work
*
* 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik
* - indentation fixes
* - usb + input init sequence fixes
*
* 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
* - verified the lack of HID and report descriptors
* - verified that ALL buttons WORK
* - fixed d-pad to axes mapping
*
* 2002-07-17 - 0.0.5 : simplified d-pad handling
*
* 2004-10-02 - 0.0.6 : DDR pad support
* - borrowed from the XBOX linux kernel
* - USB id's for commonly used dance pads are present
* - dance pads will map D-PAD to buttons, not axes
* - pass the module paramater 'dpad_to_buttons' to force
* the D-PAD to map to buttons if your pad is not detected
