The Texas Instruments OHCI-konformer IEEE 1394-Hostcontroller connects Windows to compatible FireWire devices through a Texas Instruments IEEE 1394 controller. Its Microsoft-provided driver enables the operating system to recognize the controller and communicate with attached equipment, such as digital camcorders, external storage, and audio interfaces.

Key Features

• IEEE 1394 connectivity: Provides the host-controller support needed to use compatible FireWire peripherals connected to your computer.
• OHCI support: Works with the Open Host Controller Interface standard used by compatible IEEE 1394 controllers.
• Windows integration: Allows Windows to manage the controller through Device Manager and handle connections to supported peripherals.
• Support across Windows versions: Driver options are available for Windows 10, Windows 8.1, Windows 7, Windows Vista, and Windows XP. Select a package that matches your operating system and system architecture.

How to Install

1. Check your system and controller. Open Device Manager and locate the controller under “IEEE 1394 Bus host controllers.” Confirm that it is the Texas Instruments OHCI-konformer IEEE 1394-Hostcontroller, and check whether your Windows installation is 32-bit or 64-bit.

1. Choose a compatible driver. Download the Microsoft driver package intended for your Windows version and controller hardware. If the download lists supported hardware IDs, compare them with those shown in the device’s Properties under the Details tab.

1. Prepare the driver files. Extract the download if it is compressed. Save any open work and temporarily disconnect attached FireWire peripherals before updating the host-controller driver.

1. Install the update. Run the supplied installer if one is included. Otherwise, right-click the controller in Device Manager, choose the driver update option, and browse to the extracted driver folder. Follow the prompts; wording varies between Windows versions.

1. Restart and test the connection. Restart if prompted, reconnect your FireWire device, and check that the controller appears without a warning icon. Test the peripheral in its usual application.

Windows may already include a suitable Microsoft IEEE 1394 driver, so a separate download is not always necessary. Some FireWire audio interfaces and older peripherals also require their own drivers or a specific host-controller driver configuration. If a device remains undetected, check its manufacturer’s compatibility guidance as well as the cable, power supply, and FireWire port.
