Windows may automatically assign a legacy driver that fails to enumerate. Always use the vendor’s signed driver. If you are working with Cisco systems (like CUCM 12

The driver may be fully functional, but communication will fail if the software application settings do not match the physical device hardware constraints. Ensure both sides are explicitly configured to the exact same: (e.g., 9600) Data Bits (typically 8) Parity (None, Odd, or Even) Stop Bits (typically 1) Security and Best Practices

Modern and legacy serial drivers share several core functionalities designed to ensure data integrity: Why You Need the SCI-U2S Driver Windows may

Typically set to 8 bits for standard data packets.

Another software background process is locking the COM port.
