Leadtek USB-to-Serial Port (COM5) Driver

The Leadtek USB-to-Serial Port (COM5) driver enables Windows to communicate with compatible Leadtek USB-to-serial hardware, allowing applications to access a connected serial device through a COM port. You may need it when setting up the adapter for the first time, reinstalling Windows, or troubleshooting an adapter that appears as an unknown device in Device Manager.

Key Features

• USB-to-serial communication: Provides the driver support needed for compatible software to exchange data with equipment connected through the adapter.
• COM port access: Makes the adapter available as a serial port in Windows. Although the device name includes COM5, Windows may assign a different port number on your computer.
• Support for listed Windows versions: Intended for Windows 10, 8.1, 7, Vista, and XP; check the individual package details for your OS and 32-bit or 64-bit architecture.
• Device recognition: Installing the correct package can resolve missing-driver issues and allow Windows to identify the adapter properly.

How to Install Leadtek USB-to-Serial Port (COM5) Driver

1. Confirm your hardware and Windows version. Open Device Manager and locate the adapter under Ports (COM & LPT), Other devices, or USB controllers. If necessary, check its hardware IDs under Properties > Details to help verify the driver match.
2. Choose a compatible package. Before starting your Leadtek USB-to-Serial Port (COM5) driver download for Windows, confirm the package supports your adapter and operating system. If comparing Windows 10/11 compatibility, note that Windows 11 is not included in the supported OS list provided here.
3. Download and extract the files. Select the latest version explicitly compatible with your hardware. For any free download, verify the source and review available publisher or digital-signature information before running it.
4. Install the driver. Follow the package instructions, including any guidance on when to connect the adapter. If no installer is included, use Device Manager’s driver-update option to browse to the extracted driver folder.
5. Check the connection. Restart if prompted, then confirm that the adapter appears without a warning icon. Select its assigned COM port in your serial application and match the communication settings required by your connected equipment.

Keep the driver updated when a compatible release addresses a problem or supports a system change. Before you update a working installation, review compatibility information and retain the previous installer so you can restore your setup if needed.
