Uniden USB to UART Bridge Controller (COM4) Driver

The Uniden USB to UART Bridge Controller (COM4) driver lets Windows communicate with compatible Uniden America hardware through a USB-to-serial connection.

The driver provides the communication interface; you may also need software designed for your specific Uniden device.

• Virtual COM port access: Makes the connection available as a serial port that supported applications can select.
• Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP; check the individual package for supported editions and system architecture.

How to Install Uniden USB to UART Bridge Controller (COM4) Driver

1. Check your Windows version. Confirm your operating system and whether it is 32-bit or 64-bit. For Windows 10/11 systems, note that Windows 10 is listed as supported, but Windows 11 compatibility should be verified with Uniden before installation.
2. Choose the correct package. Before starting your Uniden USB to UART Bridge Controller (COM4) driver download for Windows, verify that the package matches your hardware and operating system. Look for the latest version compatible with your device, and use a trusted source when choosing a free download.
3. Install the driver. Extract the downloaded archive if necessary, then follow the included installation instructions. If there is no installer, open Device Manager, locate the controller, choose Update driver, and browse to the extracted driver folder.
4. Connect and verify. Follow any instructions about when to attach the USB device. After installation, check Device Manager under Ports (COM & LPT) and confirm that the controller appears without a warning icon.
5. Select the assigned port. In your compatible application, choose the COM port shown in Device Manager. Although the device name includes COM4, Windows may assign a different port number.

Keep the driver updated when Uniden provides a compatible release that addresses connection problems or operating-system changes. Before you update, review the package details and retain a working installer in case you need to restore your previous setup.
