Alex knew that to get the device working, they needed to develop a custom driver. After researching the available options, Alex decided to create a KMDF (Kernel-Mode Driver Framework) HID (Human Interface Device) minidriver. This type of driver would allow the touch I2C device to be recognized as a HID device, enabling Windows to automatically load the driver and provide a seamless user experience. Alex began by setting up the development environment,

Alex began by setting up the development environment, installing the Windows Driver Kit (WDK) and the Windows SDK. They then created a new KMDF driver project using the WDF (Windows Driver Framework) template. // Usage Page (Generic Desktop) 0x15

// Copy the HID descriptor to the buffer RtlCopyMemory(buffer, hidDescriptor, sizeof(hidDescriptor)); }
