The Controller host compatibile OHCI 1394 LSI driver enables Windows to communicate with an LSI-based IEEE 1394 host controller, commonly known as a FireWire controller. This Microsoft driver supports the connection between the controller and compatible peripherals, such as digital video cameras, external storage devices, and audio interfaces.

Key Features

• Provides Windows support for an OHCI-compatible IEEE 1394 controller, allowing the operating system to recognize and manage the hardware.
• Enables FireWire data communication with connected devices, subject to peripheral compatibility and any additional device-specific software requirements.
• Integrates with Windows Device Manager for checking controller status, updating the driver, and troubleshooting recognition problems.
• Supports driver configurations for Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches your Windows version and system architecture, as one download may not cover every listed operating system.

How to Install

1. Confirm your hardware and Windows version. Open Device Manager and locate the controller under “IEEE 1394 Bus host controllers” or, if it is not recognized, under “Other devices.” Check its hardware IDs in Properties and confirm whether your Windows installation is 32-bit or 64-bit.

1. Select the appropriate driver. Download the Microsoft driver package listed for the Controller host compatibile OHCI 1394 LSI only after verifying its supported operating systems and hardware IDs. Extract the files if the download is compressed.

1. Install through Device Manager. Right-click the controller and select “Update driver” or “Update Driver Software.” Choose the option to browse your computer, then point Windows to the extracted driver folder. In Windows XP, use the Hardware Update Wizard to specify the driver location.

1. Complete the installation. Follow the prompts and restart Windows if requested. If Windows reports that a suitable driver is already installed, check the controller’s status before attempting to replace it.

1. Test your FireWire connection. Reconnect a compatible peripheral and confirm that the controller has no warning icon in Device Manager. If the peripheral still does not work, check its power, cable, and any separate driver or application it requires.

Some older FireWire equipment may require a legacy 1394 driver configuration on certain Windows versions. Consult the peripheral manufacturer’s guidance before switching drivers.

Common Issues and Fixes

• Install fails or shows Code 10/28: Remove any existing third-party 1394 drivers, reboot, then use Device Manager → Update driver → Browse → Let me pick → Microsoft 1394 OHCI Compliant Host Controller. Avoid forcing an OEM LSI package if Windows already has the inbox OHCI driver.
• Device not detected: Reseat the PCI/PCIe card, check BIOS for enabled IEEE 1394, try another FireWire cable/port, and run Device Manager → Scan for hardware changes. Confirm the card appears without a yellow warning icon.
• Version conflicts: Uninstall older LSI/VIA 1394 driver packages, delete leftover driver entries, and roll back to the Microsoft OHCI driver. Do not mix 1394a/1394b OEM utilities with the inbox driver.
