The OHCI-konformer IEEE 1394-Hostcontroller is an OHCI-compliant host controller that connects a Windows PC to IEEE 1394, commonly known as FireWire, equipment. Its Microsoft driver allows Windows to recognize the controller and communicate with compatible devices such as digital camcorders, external storage drives, and audio interfaces.

Key Features

• FireWire controller support: Enables Windows to manage an OHCI-compliant IEEE 1394 controller and its connected devices.
• Data transfer handling: Provides the host-side communication needed for tasks such as transferring video footage or accessing compatible FireWire storage.
• Windows integration: Works with Windows hardware management so you can check controller status and troubleshoot connection issues through Device Manager.
• Support across Windows versions: Driver availability covers Windows 10, 8.1, 7, Vista, and XP. Select a package that matches your specific Windows version and system architecture; one package may not support every listed system.

How to Install

1. Check your system details. Confirm your Windows version and whether it is 32-bit or 64-bit. Open Device Manager and locate the controller under “IEEE 1394 Bus host controllers.” If it is not recognized, it may appear under “Other devices.”
2. Choose a compatible driver. Review the download’s compatibility information for the OHCI-konformer IEEE 1394-Hostcontroller. Use a trusted source and avoid installing a package intended for a different operating system or controller.
3. Prepare the files. Extract the download if it is compressed. Close applications using FireWire equipment, and safely disconnect external storage before changing the controller driver.
4. Install the driver. Run the included installer, if provided. Otherwise, right-click the controller in Device Manager, select the driver update option, and browse to the extracted driver folder.
5. Restart and test. Restart Windows if prompted, reconnect your FireWire equipment, and check that the controller appears without a warning icon. Test the connected device in its usual application.

Some FireWire peripherals also require their own drivers or software. If the controller is working but a connected device is unavailable, check that device’s requirements, cable connection, and power supply before replacing the host-controller driver.

Common Issues and Fixes

• Install fails or rolls back: Windows may reject an older IEEE 1394 package due to driver signing or a mismatched INF. Remove any third-party 1394 driver, uninstall the device in Device Manager, then let Windows install its built-in OHCI IEEE 1394 host controller driver.
• Device not detected: Check that the IEEE 1394 controller is enabled in BIOS/UEFI and not disabled in Device Manager. Try another FireWire cable/port and avoid unpowered hubs; then scan for hardware changes.
• Version conflicts/code 10 or 12: Multiple 1394 drivers (legacy vs. OHCI) can conflict. Uninstall the device, delete the driver software, reboot, and reinstall only the Microsoft OHCI driver rather than a vendor legacy package.
