=== Definition of a device ===
According to the HID specification, a device is described, during the report mode, as a set of controls or group of controls.
Controls are matched by a field containing the data, and another containing a usage tag.
Each usage tag is described in the spec as the constructor suggested use of the data described in the report mode.

The {{Crossreference|selfref=no|HID Descriptor Tool ([[#External links]])}} is a Windows app that can be used to generate all the descriptors associated with a HID device (see link below). It performs syntax checking, and can generate C, C Header and binary files for the HID descriptors. Its text-based Usage Table definion files can also be easily extended to define proprietary Usages (control types) or Usage Tables (the set of Usages associated with a device or feature).
