The OHCI Compliant IEEE 1394 Host Controller driver from Microsoft enables Windows to communicate with compatible FireWire hardware through your computer’s IEEE 1394 controller. It supports the connection between the controller and devices such as digital camcorders, external drives, and audio equipment, although some peripherals may also require their own drivers.

Key Features

• IEEE 1394 controller support: Allows Windows to recognize and operate host controllers that follow the Open Host Controller Interface (OHCI) standard.
• FireWire device communication: Provides the controller-level support needed to exchange data with compatible IEEE 1394 peripherals.
• Windows integration: Works with Device Manager and Windows hardware detection to manage the controller and report driver or device issues.
• Support across Windows versions: Microsoft provides IEEE 1394 support for Windows 10, 8.1, 7, Vista, and XP, with driver availability and installation requirements varying by operating system and hardware.

How to Install

1. Confirm the controller and Windows version. Open Device Manager and look under “IEEE 1394 Bus host controllers.” Check that the listed hardware matches the OHCI Compliant IEEE 1394 Host Controller, then confirm your Windows version and whether it uses a 32-bit or 64-bit architecture.

1. Check for an existing driver. Windows may already include a suitable Microsoft driver. Review the controller’s status in Device Manager and check Windows Update before installing a separate package.

1. Choose a compatible package if needed. Use only a driver intended for your operating system and controller. A package for Windows XP or Vista should not be assumed to work on Windows 7, 8.1, or 10. Extract the downloaded files if they are compressed.

1. Install or update the driver. Run the supplied installer, if available, or right-click the controller in Device Manager and select the driver update option. Choose to browse your computer, point Windows to the extracted driver folder, and follow the prompts. Menu wording varies by Windows version.

1. Restart and test the connection. Restart your computer if requested, reconnect your FireWire device, and check for warning icons in Device Manager. If the controller is working but a peripheral is not detected, verify the cable, power supply, and any device-specific software requirements.

Common Issues and Fixes

• Install fails or Code 10/28/43: Older OEM 1394 packages often won’t install on Windows 10/11. Remove any third-party FireWire driver, reboot, then use Device Manager → Update driver → Search automatically for the Microsoft 1394 OHCI driver.
• Device not detected: Confirm the FireWire cable and port work, check that IEEE 1394 is enabled in BIOS/UEFI, and test another cable/port. Avoid unpowered hubs; use a direct host-controller connection.
• Version conflicts with legacy 1394 drivers: Uninstall the device and select “Delete the driver software,” reboot, then rescan hardware. Let Windows install the matching 1394 OHCI driver instead of mixing legacy and current 1394 stacks.
