DUAL USB ADAPTER HS (COM4) Driver

The DUAL USB ADAPTER HS (COM4) driver enables Windows to recognize the Kondo Kagaku USB adapter and make its assigned COM port available to compatible software. You may need it when setting up the adapter for the first time, reinstalling Windows, or troubleshooting a device that appears as unknown in Device Manager.

Key Features

• USB device recognition: Helps Windows identify the adapter so compatible applications can access it.
• COM-port access: Supports communication through the adapter’s assigned serial port. Although the device name includes COM4, Windows may assign a different port number on your computer.
• Support for listed Windows systems: Intended for Windows 10, 8.1, 7, Vista, and XP; check the individual package for your operating system and 32-bit or 64-bit architecture.
• Driver recovery and maintenance: Installing the appropriate package can resolve problems caused by a missing or incorrectly installed driver.

How to Install DUAL USB ADAPTER HS (COM4) Driver

1. Check your Windows version. Confirm your operating system and whether it is 32-bit or 64-bit. If you are comparing Windows 10/11 compatibility, note that Windows 11 is not included in this device’s listed supported systems.
2. Choose the matching package. Before starting a DUAL USB ADAPTER HS (COM4) driver download for Windows, verify the vendor, supported systems, and package details. Choose a trusted source, and confirm that any free download offer contains the driver rather than an unrelated utility.
3. Prepare the files. Extract the download if it is compressed, and read any included instructions. Follow the package’s guidance on when to connect the USB adapter.
4. Install the driver. Run the supplied installer if one is provided. Otherwise, open Device Manager, locate the adapter, select the option to update its driver, and browse to the extracted driver folder.
5. Verify the connection. Restart Windows if prompted, then check Device Manager for the adapter and any warning icons. Select the assigned COM port in your compatible application; use COM4 only if that is the port Windows shows.

Keep the driver updated by checking for the latest version that explicitly supports your adapter and Windows edition. An update may address documented compatibility issues, but avoid replacing a working driver with an unverified package. If connection problems persist, also check the USB cable, port assignment, and application settings.
