HID_DESCRIPTOR-Struktur (hidport.h)

Die HID_DESCRIPTOR-Struktur stellt einen HID-Deskriptor für ein HIDClass-Gerät dar.

Syntax

typedef struct _HID_DESCRIPTOR {
      UCHAR                     bLength;
      UCHAR                     bDescriptorType;
      USHORT                    bcdHID;
      UCHAR                     bCountry;
      UCHAR                     bNumDescriptors;
  struct {
        UCHAR  bReportType;
        USHORT wReportLength;
  } _HID_DESCRIPTOR_DESC_LIST;
      _HID_DESCRIPTOR_DESC_LIST DescriptorList[1];
} HID_DESCRIPTOR, *PHID_DESCRIPTOR;

Hinweise

Der HID-Klassentreiber verwendet eine IOCTL_HID_GET_DEVICE_DESCRIPTOR-Anforderung , um die HID-Deskriptor eines Geräts von einem HID-Minidriver abzurufen.

Informationen zu HID-Deskriptoren finden Sie auf der Website usb Implementers Forum (Universal Serial Bus) standard Device Class Definition for Human Interface Devices (HID).
