The Texas Instruments OHCI Compliant IEEE 1394a Host Controller driver enables Windows to communicate with the computer’s FireWire interface and connected IEEE 1394 devices. For Point Grey Research imaging setups, a compatible controller driver helps provide the connection needed for supported FireWire cameras to work with their camera software.

Key Features

• IEEE 1394a connectivity: Provides operating-system support for the host controller used to connect compatible FireWire equipment.
• OHCI controller support: Allows Windows to manage the controller through the Open Host Controller Interface standard.
• Support for camera workflows: Supplies the controller-level connection used by compatible Point Grey Research FireWire cameras. Camera-specific drivers and acquisition software may also be required.
• Windows compatibility options: Driver selection depends on your system. Check that the package explicitly supports your version of Windows 10, 8.1, 7, Vista, or XP, along with its 32-bit or 64-bit architecture.

How to Install

1. Identify the controller and Windows version. Open Device Manager and look under “IEEE 1394 Bus host controllers.” Confirm the controller name; if it appears as an unknown device, check its hardware IDs in Properties before choosing a download.

1. Choose a matching driver package. Review the package documentation for support for the Texas Instruments OHCI Compliant IEEE 1394a Host Controller, your Windows edition, and your Point Grey Research camera setup. Do not assume one package supports every listed operating system.

1. Prepare for installation. Close camera acquisition applications and disconnect external FireWire devices if the installation instructions recommend it. Extract the downloaded archive, if necessary, and review any included setup notes.

1. Install the driver. Run the supplied installer with administrator privileges. If the package contains driver files rather than an installer, use Device Manager’s “Update Driver” option and browse to the extracted folder. Follow any package-specific instructions about selecting a controller driver.

1. Restart and verify operation. Restart Windows if prompted, then check that the controller appears without a warning icon in Device Manager. Reconnect your camera and test it with compatible acquisition software. If the controller works but the camera is not detected, check the camera driver, FireWire cable, and power requirements before replacing the controller driver.

Common Issues and Fixes

• Install fails or rolls back: Verify you are using the Point Grey/TI OHCI IEEE 1394a package for the correct Windows version and architecture. If Windows blocks an unsigned legacy driver, temporarily disable driver signature enforcement, then rerun the installer as administrator.
• Controller not detected: Reseat the FireWire card in a supported PCI/PCIe slot, check any required power connection, and confirm IEEE 1394 is enabled in BIOS. Use Device Manager > Scan for hardware changes; if a warning icon appears, uninstall the device and restart.
• Version conflicts or camera dropouts: Windows may load the generic `1394ohci.sys` instead of
