CHINO USB to UART Bridge Controller (COM3) Driver

The CHINO USB to UART Bridge Controller (COM3) driver lets Windows communicate with compatible Chino hardware through a USB-to-serial connection. It is needed when your connected device is not recognized, appears with a warning in Device Manager, or cannot communicate with software that uses a serial COM port.

Key Features

• USB-to-UART communication: Provides the driver interface needed for compatible applications to exchange serial data with the connected hardware.
• Virtual COM port access: Allows serial communication software to access the device through an assigned port, such as COM3. The actual port number may differ between computers.
• Windows compatibility: Listed supported systems include Windows 10, Windows 8.1, Windows 7, Windows Vista, and Windows XP. Select a package that matches your Windows version and system architecture.
• Device identification: Helps Windows recognize the bridge controller so you can check its status and COM port assignment in Device Manager.

How to Install CHINO USB to UART Bridge Controller (COM3) Driver

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. If several similar drivers are available, compare the device’s hardware IDs in Device Manager with the package’s supported devices.
2. Choose a compatible package. Before starting a CHINO USB to UART Bridge Controller (COM3) driver download for Windows, review the compatibility details. For Windows 10/11 systems, note that Windows 10 is listed as supported, but Windows 11 support is not confirmed here.
3. Download and extract the files. Use a trusted source for a free download, and choose the latest version that explicitly supports your hardware and operating system. Extract the archive if necessary.
4. Install the driver. Run the included installer and follow its instructions. If no installer is provided, open Device Manager, right-click the controller, select Update driver, and browse to the extracted driver folder.
5. Verify the connection. Restart if prompted, then check Device Manager for warnings and note the assigned COM port. Select that same port in your serial application and use the communication settings required by your connected equipment.

Keep the driver updated when a compatible release addresses connection problems or supports a system change. Before you update a working installation, review the release notes and retain the existing installer so you can restore the previous setup if needed.
