If a device is dual-booted, the firmware might be updated by Android in a way that Windows fails to recognize. Reinstalling the Windows driver is often necessary after returning to Windows. Conclusion Conclusion To ensure optimal calibration of a touch

To ensure optimal calibration of a touch I2C device using a KMDF HID minidriver, follow these best practices:

Run !wdfkd.wdfverifier in WinDbg. The best drivers pass all KMDF rule checks (e.g., WdfDeviceInitApi , RequestReuse ). Calibration IOCTLs must never leak WDFREQUEST objects.
