OBD2-Datalogger in DFU Mode Driver

The OBD2-Datalogger in DFU Mode driver allows Windows to recognize the device’s USB firmware-update interface so compatible software can communicate with it. Associated with STMicroelectronics USB technology, this driver is intended for users whose OBD2 datalogger appears in Device Manager in DFU (Device Firmware Upgrade) mode during firmware maintenance or recovery.

Key Features

• USB device recognition: Helps Windows identify the datalogger’s DFU interface rather than leaving it listed as an unknown USB device.
• Firmware-tool communication: Provides the connection needed by a compatible firmware utility to access the device. The driver itself does not supply or update the datalogger’s firmware.
• Support for listed Windows systems: Choose a package intended for Windows 10, 8.1, 7, Vista, or XP, matching your system’s 32-bit or 64-bit architecture.
• Dedicated update-mode access: Supports the firmware-update interface, which may require a different driver from the one used for normal vehicle diagnostics or data logging.

How to Install OBD2-Datalogger in DFU Mode Driver

1. Check your system and device. Confirm your Windows version and architecture, then locate the datalogger in Device Manager. Check its hardware IDs against the driver package’s supported devices.
2. Choose a compatible package. Before starting an OBD2-Datalogger in DFU Mode driver download for Windows, review the compatibility notes and source. If selecting a free download, use a trusted source and verify that it matches your hardware.
3. Prepare the connection. Extract the downloaded archive if necessary. Connect the datalogger directly to a USB port and follow its manufacturer’s instructions for entering DFU mode.
4. Install the driver. Run the supplied installer, or right-click the device in Device Manager, select Update driver, and browse to the extracted driver folder. Follow the prompts without bypassing driver-signature warnings.
5. Verify recognition. Check that Device Manager no longer shows a driver-related warning, then open the manufacturer-recommended firmware utility. Use only firmware intended for your exact datalogger model.

Keep the driver updated when the manufacturer recommends an update or when a newer compatible release addresses a connection problem. The latest version is not necessarily suitable for every older Windows system. For Windows 10/11 installations, verify compatibility separately: Windows 10 is listed for this device, but Windows 11 support is not confirmed by the supplied information.
