When you pinch a photo to zoom, you are not thinking about report descriptors, usage tables, or collection applications. You are thinking about the photo. And that cognitive seamlessness is the driver’s only metric of success.

When Windows sees a HID-compliant touch driver, it doesn't need to know the screen's voltage ranges or i2c bus addresses. It simply asks: "Are you a digitizer? What are your capabilities? Send me events." The driver responds with a HID Report Descriptor—a tiny, self-contained grammar book explaining exactly what kind of data will flow. When you pinch a photo to zoom, you

A device is not born HID-compliant; it must be made so. The hardware manufacturer must embed a tiny microcontroller that does nothing but convert raw touch data into the rigid, beautiful syntax of HID reports. This is a sacrifice of uniqueness for the sake of universality. Your custom multi-touch grid might be brilliant, but if it doesn't output HID packets, the OS will treat it as a brick. "I don't care if you're a Synaptics, an
