Why the “CU” Matters (8811AU vs. 8811BU vs. 8811CU)

Many online forums mistakenly suggest drivers for the 8811AU or 8812BU. Do not use those. The “CU” variant uses a different USB ID (often 0BDA:C811 or 0BDA:C82C), which requires a dedicated driver. Using an incorrect driver will cause the device to show up as an "Unknown USB Device" or fail to start with Code 10.
