series) requires precise handling of hardware coordinate mapping. When touch input is inverted, offset, or restricted to a small portion of the screen, it often indicates a mismatch between the digitizer's firmware reports and the OS's expected HID descriptor. Understanding Calibration in HID over I2C HID over I2C protocol Communicates over the Serial Peripheral Bus (SPB) using

If the touch is functional but slightly off, you can calibrate it in the registry, though this is less effective than firmware calibration: kmdf hid minidriver for touch i2c device calibration best

For high-report-rate touch screens, configure a WDFIOTARGET with a continuous reader to pre-fetch touch data into a ring buffer.
