The driver version numbering reveals important compatibility information:
The CipherLab 308 is a compact, efficient device designed to convert USB signals to RS232 serial signals, enabling communication between a computer and devices such as barcode scanners, printers, and other serial-based peripherals. This converter is particularly useful in environments where older equipment with RS232 interfaces still plays a critical role.
Open Device Manager and expand the "Ports (COM & LPT)" section. Note the COM port number (e.g., COM3) assigned to the device; you will need this for your scanning software. Common Issues cipherlab 308 usb-to-rs232 interface converter driver
Completely uninstall the device from Device Manager, check the option to "Delete the driver software for this device," restart the computer, and execute an updated, WHQL-signed driver installer package matching your OS architecture. Data Corruption or Missing Characters

Most CipherLab 308 converters do not use a proprietary CipherLab chip. They typically rely on third-party chipsets, most notably the Prolific PL-2303 series or the Silicon Labs CP210x series. This means the "official" driver may actually be a universal Prolific driver.
Locate the entry corresponding to your adapter (e.g., Silicon Labs CP210x USB to UART Bridge (COMx) or CipherLab USB-to-RS232 Converter (COMx) ). Most CipherLab 308 converters do not use a
Some legacy POS (Point of Sale) or inventory management software applications can only read lower COM ports (like COM1 or COM2 ). If Windows assigned your driver to a high number like COM12 , you can manually change it:
In the world of industrial data capture and barcode scanning, compatibility is king. Legacy systems, particularly those relying on RS232 serial communication (often called COM ports), are still the backbone of many warehouses, manufacturing floors, and point-of-sale (POS) systems. However, modern computers have largely abandoned the 9-pin serial port in favor of USB.
