HID Related Specifications
Device Class Definition HID The Device
Class Definition for HID 1.11 is intended to supplement
the USB Specification and provide HID manufacturers with the
information necessary to build USB-compatible devices. It also
specifies how the HID class driver should extract data from
USB devices. The primary and underlying goals of the HID class
definition are to:
- be as compact as possible to save device data space
- allow the software application to skip unknown
information
- be extensible and robust
- support nesting and collections
- be self-describing to allow generic software
applications
HID Usage Tables The HID
Usage Tables 1.11 document defines constants that can be
interpreted by an application to identify the purpose and
meaning of a data field in a HID report.
Usages are also used to define the meaning of groups of
related data items. This is accomplished by the hierarchical
assignment of usage information to collections.
Usages identify the purpose of a collection and the items
it contains. Each Input, Output, Feature, and/or Collection
data item within a Collection item can be assigned a purpose
with its own usage item. Usages assigned to a collection apply
to the items within the collection.
The HID Usage Tables document contains extensions to the
tables defined in the USB Device Class Definition for Human
Interface Devices. All usages pages, except the Keyboard
table, are replicated in the Usage Table document. The Usage
Table document identifies the extensions to the Keyboard usage
table.
Note: For keyboards, look at the usage table
sections in both the HID Specification and the HID Usage Table
document!
Usage Tables for Physical
Interface Devices The Device
Class Definition for PID 1.0 provides information for the
development of Physical Interface Devices. These devices
include force feedback joysticks, steering wheels, etc. It
allows peripheral and driver developers to use a common set of
HID report descriptors, device usages and reports to describe
the characteristics of a PID class device.
Usage Tables for HID Power
Devices The Usage
Tables for HID Power Devices 1.0 specification provides
information to guide implementers in using the USB logical
structures for Power Devices, OS designers, BIOS designers,
and peripheral and UPS designers can use the common
descriptors, of USB Power Device Usages and Reports.
Monitor Control Class
Specification The Monitor
Control Class 1.0 specification defines how a monitor with
a USB Monitor Control interface interacts with a USB-enabled
host system.
HID Point Of Sale Usage Tables The
HID
Point Of Sale Usage Tables 1.02 document defines usages
that apply to Point of Sale devices, in particular Barcode
Scanners and Scales.

Related HID Documentation page contains links to
documentation on Microsoft's site geared towards HID
implementation, device class support, devices, etc.

HID
Descriptor Tool This tool allows you to create,
edit and validate HID Report Descriptors. The tool also
supports a variety of output formats (.txt, .inc, .h, etc.).
DT uses ASCII based Usage Tables and supports vendor defined
pages as well. Included are Usage Table files for the HID
Usage Table document 1.0 Release Candidate 1, Monitor Class
1.0 Release Candidate 2, and Power Class Spec. Read the
included README.TXT file for more information.
HIDView This program, found in
the USBCheck, is now obsolete. Its replacement is USBCV.

Unicode The Unicode web site
( http://www.unicode.org/)
allows you to download the latest character tables for free.
Check it before you finalize a design because new ones are
always in process. The Nadine Kano book, "Developing
International Software" which was used as key reference for
Unicode, is out of print. It can still be obtained in a CD-ROM
version as part of the Microsoft Developers Network (MSDN)
subscription. Subscription information can be obtained at the
MSDN web site (msdn.microsoft.com). Or
it can be accessed for free online at the MSDN Library.
The book can be found under "Books / Developing International
Software". To get the latest LANGID definitions go to http://msdn.microsoft.com/library/default.asp?url=/library/en-us/intl/nls_8xo3.asp
. This page will change as new LANGIDs are
added. Note that the HID Primary LANGID (0x0FF) is not on
the above list, however it is permanently reserved and will
never be reassigned.
