The A133 SoC features a complex USB subsystem designed to handle modern high-speed data transfer while maintaining backward compatibility. The architecture differs slightly from legacy Allwinner chips (like the A64 or A33) due to updates in the PHY design and the specific GPIO configurations used for port switching.

Windows Update automatically installs incompatible drivers.
