Without the correct driver, the operating system sees the device only as a generic "USB Device" or "Unknown Device," rendering the sophisticated electronics of the Pi40952 useless.
Long unshielded wires from MCU to driver pins act as antennas. Fix: Add 10kΩ pull-down resistors near the driver’s input pins and use twisted pair wiring.
