The BMW Scanner 1.4.0 uses a USB-to-OBD cable with a BMW 20-pin round adapter (for older models) or just an OBD2 connector for E46/E39/E38/E53, etc.
Inside is an FTDI or CH340 USB serial chip. Most clones use CH340.
Before installing drivers, check the USB cable itself. There are two main versions of the hardware, and they require different drivers.
If you have a removable cover on the USB end of the cable, slide it off to see the color of the circuit board inside.
Follow this guide carefully. Do not plug in the scanner until instructed.

The BMW Scanner 1.4.0 (PA Soft) is a specialized diagnostic and coding tool for older BMW models like the E38, E39, E46, E53, E83, and E85. While it originally targeted Windows XP, running it on modern systems like Windows 10 or 11 requires manual driver configuration, as the scanner typically uses a generic FTDI USB chip that needs specific virtual COM port drivers.
