Brother MFC-790CW Remote Setup Port (COM3) Driver

The Brother MFC-790CW Remote Setup Port (COM3) driver helps Windows recognize the USB communication interface used by Brother’s Remote Setup software to configure the MFC-790CW multifunction printer. It is relevant if you need to manage device settings from your computer or troubleshoot a missing or unrecognized Remote Setup port.

Key Features

• Remote Setup communication: Supports the connection between compatible Brother configuration software and the device’s settings interface.
• USB interface recognition: Helps Windows identify the Remote Setup port correctly rather than leaving it listed as an unknown device.
• Legacy Windows support: Intended for compatible installations of Windows 10, 8.1, 7, Vista, and XP, subject to the operating systems supported by the selected package.
• Configuration support: Works alongside the appropriate Brother software; this port driver alone does not provide the complete printing and scanning feature set.

How to Install Brother MFC-790CW Remote Setup Port (COM3) Driver

1. Check your Windows installation. Confirm your Windows version 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 the supported OS list provided for this device.
2. Select a compatible package. Before starting your Brother MFC-790CW Remote Setup Port (COM3) driver download for Windows, check that the package explicitly supports the MFC-790CW and your operating system. Choose the latest version available for that combination, not simply the newest Brother driver.
3. Download from a trusted source. Prefer Brother’s official support resources when available. A free download should not require purchasing a third-party driver updater. The Remote Setup component may be included in a broader Brother software package rather than offered separately.
4. Run the installer. Close any open Brother utilities, launch the downloaded setup file, and follow the instructions to install the software. Connect the printer by USB when prompted, and restart Windows if requested.
5. Verify the connection. Check Device Manager for the Remote Setup interface and any warning icons, then test communication using compatible Brother Remote Setup software. Windows may assign a COM number other than COM3; a different number does not necessarily indicate a problem.

Keep the driver and associated Brother software updated with compatible releases, particularly when troubleshooting connection issues or after a Windows change. Before an update, review the package’s supported systems and installation notes to avoid replacing a working driver with an incompatible version.
