For most users and developers, the "full" driver package is bundled with the Microchip Studio (formerly Atmel Studio) or the Microchip USB Driver Package.
Windows 11 introduced stricter driver signature requirements and memory integrity checks that can sometimes block older mXT USB drivers. Whether you are a developer working with Atmel MaXTouch evaluation kits or a user trying to fix a specialized peripheral, here is how to achieve a full, stable installation. 1. Identify Your Specific mXT Hardware Download the latest installer from the official Microchip
If the automated installer fails, you may need to point Windows 11 directly to the .inf file: Open . Right-click your mXT device > Update driver .
"mXT" typically refers to the line of touchscreen controllers. Before downloading files, identify your Hardware ID : Right-click Start > Device Manager . Find your "Unknown Device" or "mXT USB Device." Right-click it > Properties > Details tab. Look for VID (Vendor ID) and PID (Product ID)
If the driver is blocked, go to Windows Security > Device Security > Core isolation details and toggle Memory integrity to Off. Note: This lowers security, so only do this if the driver is mission-critical.
