The LSI (Agere) OHCI Compliant IEEE 1394b Host Controller driver enables Windows to communicate with compatible FireWire hardware through the controller. For Point Grey Research camera setups, the appropriate driver helps establish the connection between the IEEE 1394 interface and connected imaging devices, alongside any required camera software.

Key Features

• IEEE 1394b connectivity: Supports communication through the FireWire host controller, allowing compatible cameras and other IEEE 1394 devices to connect to the computer.
• OHCI controller support: Provides the driver interface Windows needs to recognize and operate the Open Host Controller Interface–compliant hardware.
• Windows version options: Driver packages may cover Windows 10, 8.1, 7, Vista, and XP. Select a package that explicitly supports your operating system and its 32-bit or 64-bit architecture.
• Camera system integration: Provides controller-level connectivity for compatible Point Grey Research equipment. Camera-specific drivers, capture applications, or an SDK may also be necessary.

How to Install

1. Confirm the controller and Windows version. Open Device Manager and look under “IEEE 1394 Bus host controllers.” Check that the hardware matches the LSI (Agere) OHCI Compliant IEEE 1394b Host Controller, then verify your Windows version and system architecture. If the controller is unidentified, compare its hardware IDs with those listed in the driver package.

1. Choose the matching download. Select the package intended for your controller and operating system. Do not assume a driver for Windows XP or Vista will work on Windows 7, 8.1, or 10 unless compatibility is explicitly stated.

1. Prepare for installation. Extract the downloaded archive if necessary and read any included instructions. Close camera capture software, and use an administrator account to make driver changes.

1. Install the driver. Run the supplied installer if available. For a manual installation, right-click the controller in Device Manager, choose the driver update option, and browse to the extracted driver folder. Avoid forcing installation if Windows reports that the driver is incompatible.

1. Restart and test the connection. Restart the computer if prompted, then confirm that Device Manager shows the controller without a warning icon. Connect your FireWire device according to its instructions and test it with the appropriate application.

If a camera remains undetected, check its power supply, cable, and camera software before reinstalling the host controller driver.

Common Issues and Fixes

• Driver install fails or device shows Code 10/28: On Windows 8/10/11, the inbox 1394 OHCI driver may not bind correctly. In Device Manager, update the controller manually and select the 1394 OHCI Compliant Host Controller (Legacy) driver. Remove any previous Point Grey/FireWire driver package first.
• Device not detected: Reseat the PCIe card, confirm BIOS has the slot enabled, and use a known-good 1394b cable. Check camera power and try another 1394 port. In Device Manager, enable Show hidden devices to look for a stale controller entry.
• Version conflicts with Point Grey software: Uninstall old FlyCapture/FireWire driver versions and remove duplicate 1394 host controller entries. Install the FlyCapture SDK version matching your camera, and do not mix legacy and current 1394 drivers on the same system.
