RadioShack Gigaware USB To Serial Cable Driver

The RadioShack Gigaware USB To Serial Cable driver enables Windows to communicate with compatible serial equipment through the cable’s USB connection. If you use this Radio Shack adapter with a serial printer or another RS-232 device, you need a compatible driver so your computer can recognize the adapter and assign it a COM port.

Key Features

• USB-to-serial communication: Allows compatible software to exchange data with a connected serial device through the Gigaware cable.
• COM port access: Makes the adapter available as a serial port that you can select in printer utilities, terminal applications, or other device software.
• Configurable serial settings: Supports access to communication settings such as baud rate, parity, and flow control, where available through Windows or your application.
• Windows driver setup: Provides the software needed to recognize supported adapter hardware. For Windows 11, 10, 8, or 7, check the individual package’s compatibility before installation, especially on Windows 10/11.

How to Install RadioShack Gigaware USB To Serial Cable Driver

1. Identify your adapter and Windows version. Check the cable’s model information and your system type. Gigaware adapters may require different packages depending on their hardware revision.
2. Choose a compatible package. Before starting your RadioShack Gigaware USB To Serial Cable driver download for Windows, confirm that the listed operating system and hardware match your cable. Select a trusted free download and look for the latest version compatible with your adapter.
3. Extract and install the driver. Unzip the downloaded files if necessary. Run the included installer and follow its instructions, including any guidance about when to connect the cable. If no installer is included, use Device Manager’s “Update driver” option and browse to the extracted folder.
4. Connect the adapter and verify detection. Open Device Manager and look under “Ports (COM & LPT)” for the adapter and its assigned COM number. Restart Windows if prompted.
5. Configure your connected equipment. Select the same COM port in your application, match the serial settings to your equipment, and test communication. A serial printer may also need its own printer driver.

Keep the driver updated when a compatible release addresses connection problems or Windows compatibility. Before you update, verify support for your exact cable rather than assuming the newest package is suitable for every Gigaware adapter.

Common Issues and Fixes

• Install fails or shows Code 10/28: Uninstall any existing Prolific PL2303 driver in Device Manager (View > Show hidden devices), reboot, then run the Gigaware/PL2303 installer as administrator. Use a signed driver compatible with your Windows version.
• Device not detected/no COM port: Try another USB port and cable; check Device Manager for “Prolific USB-to-Serial Comm Port” under Ports. If it appears as Unknown Device, reinstall the USB-to-serial driver and rescan hardware.
• Version conflicts after Windows Update: Windows may replace the working PL2303 driver with an incompatible newer version. Roll back the driver or reinstall the RadioShack/Gigaware-compatible driver, then confirm the assigned COM port in Device Manager.
