GHI Boot Loader Interface (COM3) Driver

The GHI Boot Loader Interface (COM3) driver helps Windows recognize the USB boot loader interface on compatible Ghi hardware and make it available as a serial COM port. It is intended for users who need to connect a device in boot loader mode for firmware loading, recovery, or development with compatible tools.

Key Features

• USB interface recognition: Helps Windows identify the connected boot loader interface rather than leaving it listed as an unknown device.
• Serial port access: Makes the interface available to compatible software through a COM port. Although the device name includes COM3, Windows may assign a different port number.
• Boot loader communication: Provides the connection needed by compatible firmware utilities; the driver itself does not contain or update the device’s firmware.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that explicitly matches your Windows version and system architecture.

How to Install GHI Boot Loader Interface (COM3) Driver

1. Check your system. Confirm your Windows version and whether it is 32-bit or 64-bit. For Windows 10/11 systems, note that Windows 10 is listed as supported, while Windows 11 compatibility should be verified separately.
2. Select a suitable package. Before starting the GHI Boot Loader Interface (COM3) driver download for Windows, review the package’s compatibility information. Choose the latest version that supports your hardware and operating system, and use a trusted source when selecting a free download.
3. Prepare the hardware. Extract the downloaded files if necessary. Connect the device using a data-capable USB cable and follow its documentation to enter boot loader mode.
4. Install the driver. Run the included installer, if provided. Otherwise, open Device Manager, locate the boot loader or unknown USB device, select Update driver, and browse to the extracted driver folder. Do not bypass security warnings for an unverified package.
5. Verify the connection. Check Device Manager for the recognized interface and note its assigned COM port. Select that port in your compatible firmware tool, following the hardware’s instructions before attempting any firmware operation.

Keep the driver updated when a compatible release addresses connection problems or adds support you need. Before you update a working installation, review the release notes and retain the previous installer so you can restore your setup if necessary.
