FX-USB-AW/FX3U-USB-BD Driver

The FX-USB-AW/FX3U-USB-BD driver enables Windows to recognize the FTDI-based USB interface used to connect a computer to compatible Mitsubishi FX-series PLC hardware. It is intended for technicians, automation engineers, and users who need a working USB connection for supported PLC programming and maintenance software.

Key Features

• USB communication support: Provides the driver layer needed for compatible software to communicate with the connected interface.
• Virtual COM port access: Allows applications that use serial communication to access compatible FTDI hardware through an assigned Windows COM port.
• Windows compatibility: Supports Windows 10, 8.1, 7, Vista, and XP when the appropriate driver package is selected for the operating system and architecture.
• Connection troubleshooting: Installing the correct driver can help resolve missing-device or unrecognized-interface issues caused by an absent or incompatible driver.

How to Install FX-USB-AW/FX3U-USB-BD Driver

1. Check your Windows version and system type. Confirm whether your computer uses a 32-bit or 64-bit operating system before choosing an FX-USB-AW/FX3U-USB-BD driver download for Windows. For Windows 10/11 systems, note that Windows 10 is listed as supported here; Windows 11 compatibility must be verified separately.
2. Select a suitable package. Look for the latest version that explicitly supports your device and Windows release. If choosing a free download, use a trusted source and check any supplied compatibility notes before opening the files.
3. Prepare the driver files. Extract the archive if necessary and read the included instructions. If the package contains an installer, follow its guidance on when to connect the USB interface.
4. Install the driver. Run the supplied installer, or open Device Manager, locate the connected interface, select Update driver, and browse to the extracted driver folder. Administrator permission may be required.
5. Verify the connection. Check Device Manager for warning symbols and, if a COM port is assigned, select that port in your PLC software. Restart Windows if prompted, then test communication with the compatible PLC.

Keep the driver updated when a compatible update addresses a connection issue or supports a change to your system. Before replacing a working driver, review the release notes and confirm support for your Windows version—especially on older systems, where the latest version may not be the right choice.
