The IOCTL_HID_ACTIVATE_DEVICE request activates a HIDClass device, which makes it ready for I/O operations. User-mode applications and other kernel-mode drivers can only communicate with HID collections by using the HIDClass support routines and HID class driver IOCTLs. Only the HID class driver sends these IOCTLs to a HID minidriver.
HID Minidriver IOCTLsĪ HID minidriver must handle a set of IOCTLs. The header defines IOCTLs that a HID minidriver must support. HID minidrivers use only the HidRegisterMinidriver routine.įor Windows 8.1 Microsoft introduced the new API which lets you write Windows apps that access HID devices. However, kernel-mode drivers can only call HidP_Xxx routines. There are system-supplied routines that user-mode applications, kernel-mode drivers, and HID minidrivers use to operate devices in the HIDClass device setup class.Īs a general rule, user-mode applications can use the HidD_Xxx and HidP_Xxx routines. Typically, these are devices that humans use to directly control the operation of computer systems. This section contains the programming interfaces related to Human Interface Devices (or HID).
To develop Human Interface Devices (HID), you need these headers:įor the programming guide, see Human Interface Devices (HID).įor Win32 HID programming APIs, see Win32 Human Interface Devices Reference. Overview of the Human Interface Devices (HID) technology.
