The 1394 OHCI Compliant Host Controller driver from Microsoft allows Windows to communicate with compatible IEEE 1394, also known as FireWire, controller hardware. It supports the connection between your PC and FireWire peripherals such as digital video cameras, external storage devices, and audio interfaces. Driver availability and installation options vary across Windows 10, 8.1, 7, Vista, and XP, so choose a package or built-in driver appropriate for your system.

Key Features

• FireWire controller support: Enables Windows to recognize and use compatible Open Host Controller Interface (OHCI) IEEE 1394 controllers.
• Peripheral communication: Provides the controller-level support needed for data exchange with connected FireWire devices. Some peripherals may also require their own drivers or software.
• Windows integration: Works with Windows hardware detection and Device Manager to support controller setup and troubleshooting.
• Support for compatible hardware: Designed for OHCI-compliant FireWire controllers, including those found on supported motherboards and expansion cards.

How to Install

1. Check your Windows version and controller. Confirm whether your system runs Windows 10, 8.1, 7, Vista, or XP, and check its 32-bit or 64-bit architecture where applicable. Open Device Manager and look under “IEEE 1394 Bus host controllers”; an unconfigured controller may appear under “Other devices.”

1. Choose a compatible driver source. Windows commonly includes a driver for OHCI-compliant 1394 controllers. Try the built-in driver or Windows Update first. If downloading a separate package, verify that it supports your Windows version and controller hardware.

1. Prepare the driver files. Extract the download if it is compressed. If the package includes an installer, follow its instructions. Avoid using a package intended for another Windows version.

1. Update through Device Manager if needed. Right-click the controller, select the driver update option, and choose either an automatic search or a manual search of the extracted driver folder. Menu wording differs between Windows versions.

1. Restart and test the connection. Restart if prompted, then confirm that the 1394 OHCI Compliant Host Controller appears without a warning icon. Connect your FireWire peripheral and test it in the relevant application. If it still fails, check the cable, peripheral power, and any device-specific driver requirements.

Common Issues and Fixes

• Install fails or device shows Code 10/28: The in-box Microsoft 1394 OHCI driver may not bind correctly. In Device Manager, right-click the controller, choose Update driver > Browse > Let me pick, and select the 1394 OHCI Compliant Host Controller entry. Restart afterward.
• Device not detected: Confirm IEEE 1394/FireWire is enabled in BIOS/UEFI and not disabled in Device Manager. Try another FireWire cable/port, power-cycle the external device, then use Scan for hardware changes. Faulty cables and unpowered enclosures are common causes.
• Version/driver conflicts: Remove any third-party 1394 driver, uninstall the controller in Device Manager (including hidden devices), reboot, and let Windows reinstall the Microsoft driver. Use Roll Back Driver if a recent update broke functionality, and match driver architecture to Windows.
