The Texas Instruments OHCI-compliant IEEE 1394 Host Controller driver lets Windows communicate with compatible FireWire hardware connected through the controller. Provided by Microsoft, this driver supports the link between the operating system and devices such as external storage, digital video cameras, and certain audio interfaces.

Key Features

• Enables Windows to recognize and use a compatible Texas Instruments IEEE 1394 host controller.
• Supports OHCI-standard FireWire communication for connected peripherals, including data transfer and device detection.
• Integrates with Windows Device Manager, where you can check controller status, update the driver, or roll back a previous installation.
• Offers driver options for Windows 10, 8.1, 7, Vista, and XP, with the correct package depending on your Windows version and system architecture.

How to Install

1. Confirm your controller and Windows version. Open Device Manager and look under “IEEE 1394 Bus host controllers.” Check that the hardware matches the Texas Instruments OHCI-compliant IEEE 1394 Host Controller. Also confirm whether your Windows installation is 32-bit or 64-bit.

1. Select the matching driver. Download a Microsoft driver package intended for your operating system and controller. A package for Windows XP or Vista should not be assumed compatible with Windows 7, 8.1, or 10.

1. Extract the files if necessary. If the download is an archive, unpack it into an accessible folder. Read any included instructions before proceeding.

1. Install the driver. If a setup program is included, follow its prompts. Otherwise, right-click the controller in Device Manager, choose the driver update option, and browse to the extracted driver folder.

1. Restart and test the connection. Restart Windows if prompted, then check Device Manager for warning icons. Connect a compatible FireWire device and verify that Windows detects it.

This driver manages the host controller, not every attached peripheral. Some FireWire devices require their own drivers or applications; if a device remains unavailable, also check its power supply, cable, and manufacturer requirements.

Common Issues and Fixes

• Device not detected (Code 10/43): Reseat the TI IEEE 1394 PCI/PCIe card, try another slot, and check that the 139
