Gigaware USB to Serial Driver

The Gigaware USB to Serial adapter lets modern computers communicate with legacy serial equipment, including older printers that rely on RS-232 connections. Installing the correct driver ensures Windows 11, Windows 10, Windows 8, and Windows 7 recognize the adapter and create a stable COM port for uninterrupted printing and data transfer.

Key Features

• Creates a reliable virtual COM port so serial printers and other RS-232 devices work smoothly with Windows 11 and Windows 10.
• Supports Plug and Play detection on Windows 8 and Windows 7, making initial setup faster and less confusing.
• Preserves consistent baud rate and flow control settings to help prevent garbled print jobs or dropped connections.
• Works with legacy serial printer cables and adapters, allowing older printing hardware to remain useful on newer systems.

How to Install

1. Download the Gigaware USB to Serial driver package for your version of Windows and extract the files to a folder you can easily find.
2. Connect the Gigaware USB to Serial adapter to an open USB port and let Windows finish any automatic detection.
3. Open Device Manager, locate the adapter under “Other devices” or “Ports (COM & LPT),” right-click it, and select “Update driver.”
4. Choose “Browse my computer for drivers,” navigate to the extracted folder, and follow the instructions to complete the installation.
5. Restart your PC, then reopen Device Manager to verify the adapter appears under Ports (COM & LPT) without a warning icon.

Common Issues and Fixes

• Driver install fails or is blocked: Windows may reject the older USB-to-serial driver. Run the Gigaware installer as administrator, reboot, and if needed temporarily disable driver signature enforcement, then reinstall.
• Device not detected / no COM port: Check Device Manager for “Unknown device” or a yellow warning. Try a different USB port (prefer rear ports), remove hubs/extensions, reseat the adapter, and reinstall the driver.
• Driver/version conflicts: Existing USB-to-serial drivers or Windows Update versions can override the Gigaware driver. Uninstall other USB-to-serial drivers and stale COM ports in Device Manager, reboot, then install the correct Gigaware driver and block automatic driver updates.
