The Texas Instruments OHCI-Compliant IEEE 1394 Host Controller driver allows Windows to communicate with compatible Texas Instruments FireWire controller hardware. This Microsoft-provided driver supports the connection between the controller and IEEE 1394 peripherals, such as compatible digital camcorders, external drives, and audio equipment.

Key Features

• OHCI controller support: Enables Windows to recognize and operate compatible Texas Instruments IEEE 1394 host controllers using the Open Host Controller Interface standard.
• FireWire device communication: Provides the controller-level support needed for data transfer with connected IEEE 1394 equipment. Some peripherals may also require their own drivers or software.
• Windows integration: Works with Windows hardware management tools, including Device Manager, to help you check controller status and troubleshoot connection problems.
• Support across Windows versions: Driver options are available for Windows 10, 8.1, 7, Vista, and XP. Select a package that explicitly matches your operating system and its 32-bit or 64-bit architecture.

How to Install

1. Identify your controller and Windows version. Open Device Manager and look under “IEEE 1394 Bus host controllers.” If the controller appears as an unknown device, check its hardware IDs in Properties before choosing a driver.
2. Select the matching driver. Confirm that the download supports your Texas Instruments OHCI-Compliant IEEE 1394 Host Controller, Windows version, and system architecture. Avoid installing a package intended for different hardware.
3. Prepare the files. Download the package and extract it if necessary. Close applications using FireWire equipment before changing the controller driver.
4. Install the driver. Run the included installer, if provided. Otherwise, right-click the controller in Device Manager, choose the driver update option, and browse to the extracted driver folder. Menu wording varies by Windows version.
5. Restart and test. Restart if prompted, then confirm that Device Manager shows no warning icon for the controller. Connect your FireWire device and test it with the appropriate application.

If Windows already recognizes the controller and your equipment works correctly, a manual driver change may not be necessary. For persistent connection issues, also check the FireWire cable, peripheral power supply, and any device-specific software requirements.

Common Issues and Fixes

• Device not detected: Check that the 1394 controller is enabled in BIOS/UEFI and seated correctly. In Device Manager, scan for hardware changes; if missing, add the “1394 OHCI Compliant Host Controller (Legacy)” driver via Add Legacy Hardware.
• Install fails: Use the Windows inbox Microsoft 1394 OHCI driver rather than an old TI package. Run Device Manager as administrator; only use “Have Disk” with an INF that matches the controller’s hardware ID. Roll back if installation breaks the port.
• Version conflicts/code 10 or 52: Uninstall the device and delete its driver, restart, then let Windows reinstall the Microsoft OHCI driver. If unstable, switch between the standard and Legacy 1394 OHCI entries; avoid mixing vendor and Microsoft packages.
