Device Class Definition HID
HID Global Acquires Access-IS, a Leading Global Provider of Miniaturized Reader Devices That Combine Key Technologies for Mission-Critical Markets August 17, 2020 02:30 AM Eastern Daylight Time. The HID class driver handles IOCTLs to support for top-level collections. Although user applications can communicate with the HID class driver by using HidDXxx HIDClass support routines, kernel-mode drivers must send the corresponding device control requests described in this section. The input and output parameters are request-specific.
Hid Global Port Devices Drivers
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:
Hid Global Port Devices Driver License Test
- 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 1.21 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!
Approved Usage Table Review Requests
Hid Global Port Devices Driver Updater
The following HID Usage Table Review Requests have been approved for implementation by the USB Device Working Group HID Committee. These Review requests assign enumeration values and recommended meaning to new Usages allocated after the publication of the HID Usage Tables v1.21. Please note that the creation of a new Usage does not imply support for that Usage by any USB HID Host vendor. Integrated Usage Table Review Requests.
