HID Config Save
Human Interface Device Configuration Save sample
Version 1.0 18 Oct 2007 Initial release.
This application is a Carbon NIB sample which demonstrate a simple game applications. It provides a number of menu options. Configure Input shows the assignment of device elements to application defined actions. The Save and load configuration allows the saving and restoring of the complete configuration to a text file. The Go
command shows using the configured inputs in a simple game like environment. Note, by using multiple Carbon event handlers and due to the HID Manager and Utilities architecture we are able to provide easy on the fly reconfiguration of input.
Requirements: Mac OS X 10.5, Xcode 3.2

Building the Sample
The sample was built using Xcode 3.2 on Mac OS X 10.6. You should be able to just open the project and choose Build from the Build menu. This will build "HID Config Save.app" in the "build/debug" or "build/release" directory.
Using the Sample
Launch "HID Config Save"
Press the "X Axis" button and then press or move a USB HID devices element (key, button, axis, etc) to assign that element to that action.
Repeat the previous step for the "Y Axis", "Thrust", and "Fire" buttons.
Click the "Save" button.
Quit and re-launch the "HID Config" application.
A window should appear. Note: the buttons should be assigned to the saved configuration.
Click on the "Play" tab.
A black view should appear; moving the HID element associated with the X or Y axis should move the dot and crosshairs in the center of the view. Interacting with the "Fire" element should change the crosshairs into (red) laser traces (from the corner of the view). Interacting with the "Thrust" element should change the dots color from yellow to green.
This demonstration application and the set of utilities is constantly evolving to both address any bugs and provide better support for developer requested features. Any suggestions and/or bugs can be directed to the Apple bug reporter at: <http://developer.apple.com/bugreporter/index.html>
We hope this helps people get up and running with the HID Manager APIs introduced in 10.5 in a quick and painless manner.
Credits and Version History
Version 5.0 27 July 2010
Element calibration properties now doubles.
Device / Element info printf's now use HIDDump[Device/Element]Info.
Version 4.0 18 Oct 2007
Update for new Leopard API's and Universal Binary.
Dropped MWCW, Project Builder and all CFM support.
Version 3.2 15 Oct 2004
Fixed a bug where HIDGetNextDeviceElement wasn't
iterating to the next sibling when returning to the top of the tree.
Reformatted for DTS template
Changed to using hu_device_t and hu_element_t
Added Intro.rtf ( may be merged into generic read me )
Added Immersion sources ( for FFB )
Version 3.1 28 Oct 2002
General cleanup for web posting.
Version 3.0 First major release since 2.0 in Dec 2K1.
Changed all references to "Kernel/IOKit/hidsystem/" to "IOKit/hid/".
Added "Queue Empty" callback test code ( it works! ).
Changed HIDSaveElementConfig => HIDSaveElementPref
Changed HIDRestoreElementConfig => HIDRestoreElementPref
GetDeviceElementNameString now uses the "New & Improved!"
HIDGetElementNameFromVendorProductUsage instead of the
Added menus and routines to rebuild the device list,
and test transaction, polling and pinging devices.
Changed the HIDBuildDeviceList call in main to NOT limit
the device list to just gamepads.
Version 2.0: Update for new interface types and include files. Added
CFM support in separate CW project. This CFM
application utilizes the HID.Bundle ( containing a MachO
dylib ). The sample is set up to look for the bundle in
the same directory as the application ( which could be
modified easily to suit developer needs ). Note, this
CFM sample application is bundled ( with the CW project
designed to put the executable in the correct place with
the correct name for the bundle ) but this is only to
support the Nib interface. There is no requirement for a
bundled application to use HID Utilities CFM support.
Version 1.1: Update. Updated a number of framework issues.
Version 1.0: Initial release. Application to demonstrate building
device list, configuring input for simple game, save and
retrieving configuration and handling input for the game.
Share and Enjoy.
