Brother MFC-665CW USB Remote Setup Port (COM3) Driver

The Brother MFC-665CW USB Remote Setup Port (COM3) driver helps Windows communicate with the remote setup interface of your Brother multifunction printer over USB. It is intended for users who need to configure supported device settings from their computer or resolve a missing remote setup port after connecting the printer.

Key Features

• Remote setup communication: Provides the USB communication interface used by compatible Brother Remote Setup software to access device settings.
• Port identification: Helps Windows recognize the remote setup interface shown as COM3. The assigned COM port number can differ between computers.
• Legacy Windows support: Look for a package specifically matching Windows 10, 8.1, 7, Vista, or XP, including the correct 32-bit or 64-bit edition.
• Part of the device software setup: Supports the configuration interface rather than replacing the separate drivers needed for printing or scanning. Despite a “Camera” category label, this entry belongs to a Brother multifunction printer.

How to Install Brother MFC-665CW USB Remote Setup Port (COM3) Driver

1. Check your Windows version. Confirm your operating system and system type before choosing a Brother MFC-665CW USB Remote Setup Port (COM3) driver download for Windows. For Windows 10/11 systems, check compatibility carefully: Windows 11 is not included in the listed supported operating systems.
2. Choose a compatible package. Find the latest version available for your exact model and Windows edition, preferably from Brother’s official support resources. If selecting a free download elsewhere, verify its source and model information before opening it.
3. Prepare the connection. Turn on the MFC-665CW and follow the package instructions about when to connect the USB cable. Avoid connecting through an unreliable USB hub.
4. Install the software. Run the installer and follow its prompts. If the package includes Brother Remote Setup, install that component as directed. Restart Windows if requested.
5. Verify recognition. Check Device Manager for the remote setup port and any warning icons, then test access through compatible Brother Remote Setup software. A port number other than COM3 does not necessarily indicate a problem.

Keep the driver updated when Brother provides a compatible update that addresses your needs. Before you update, review the supported operating systems and installation notes; a newer package for a different model or Windows release is not a suitable replacement.

Common Issues and Fixes

• Install fails or rolls back: Remove older Brother MFC-665CW software and any leftover USB Remote Setup Port entries in Device Manager, reboot, then run the latest full driver package as administrator. Disconnect other Brother USB devices during install.
• Device not detected / Remote Setup can’t connect: Confirm printer is on, USB cable is direct to PC (not hub), and use a USB 2.0 port. In Device Manager check for "Brother MFC-665CW USB Remote Setup Port"; if missing, reinstall driver and reopen Remote Setup.
• COM3 conflict or version mismatch: If another device uses COM3, change the Brother port to an unused COM number in Device Manager > Ports. Remove mixed old/new Brother drivers, then reinstall the matching package. Close apps holding the COM port.
