According to your in-house data, the product is officially compatible with Windows 10, Windows 7, Windows 8 and Windows Vista, but Windows 11 is not explicitly listed. According to the official Wacom website, there are current drivers for Windows 11, which indicates compatibility. A firmware update is not explicitly required for compatibility with Windows 11, but you should always install the latest drivers.

I'm not entirely sure whether a firmware update is necessary for compatibility with Windows 11, as the official information does not explicitly mention this. However, compatibility with Windows 11 is very likely if you use the latest drivers.
