In another example, a computer can receive remote input from a Miracast device by using the UIBC protocol. For example, consider accelerometer data from a phone that is behaving as a game controller, sent wirelessly to a PC. It can be a stream of data in the HID format that is sent by another software component for virtual hardware such as, for non-GPIO buttons or sensors. In some cases, the transport might not be supported by Windows, or the reports might not directly map to real hardware. The device sends those reports over various transports, some of which are supported by Windows, such as HID over I2C and HID over USB. The reports are in the form of HID collections and HID Usages. Learn about writing a HID source driver that reports HID data to the operating system.Ī HID input device, such as – a keyboard, mouse, pen, touch, or button, sends various reports to the operating system so that it can understand the purpose of the device and take necessary action. Virtual HID Framework Callback Functions.Load the VHF driver as the lower filter to the HID source driver in the virtual HID device stack.Write a Kernel-Mode Driver Framework (KMDF)HID source driver that submits HID Read Reports to the operating system.
