LSI OHCI Compliant IEEE 1394a Host Controller Driver

The LSI OHCI Compliant IEEE 1394a Host Controller driver enables Windows to communicate with the LSI Logic controller that manages your computer’s FireWire connection. It helps compatible IEEE 1394a peripherals, such as external storage drives and digital video equipment, connect and operate through the appropriate Windows driver stack.

Key Features

• FireWire device connectivity: Supports communication between the host controller and compatible IEEE 1394a devices, including legacy external storage hardware.
• OHCI-standard operation: Allows Windows to work with the controller through the Open Host Controller Interface, a standardized interface for managing FireWire connections.
• IEEE 1394a transfer support: Enables use of the controller’s FireWire 400 capabilities. Actual transfer speeds depend on the connected device, cable, and overall system configuration.
• Windows integration: Helps Windows recognize and manage the controller in Device Manager. For Windows 11, 10, 8, or 7, choose a driver package that explicitly supports your operating system and hardware.

How to Install

1. Confirm the 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 under Properties > Details. Also confirm whether your Windows installation is 32-bit or 64-bit.

1. Check the download’s compatibility. Select a driver intended for the LSI OHCI Compliant IEEE 1394a Host Controller and your Windows version. Do not assume a package designed for Windows 7 will also work on Windows 10 or Windows 11.

1. Prepare the driver files. Download the compatible package and extract it if necessary. Before changing drivers, safely eject any attached FireWire storage devices to avoid interrupting active transfers.

1. Install the driver. Run the included installer, if provided. Otherwise, right-click the controller in Device Manager, select “Update driver,” choose “Browse my computer for drivers,” and point Windows to the extracted folder.

1. Restart and verify operation. Restart the computer if prompted, then check Device Manager for warning icons. Reconnect a compatible FireWire device and confirm that Windows detects it. If installation fails, check the package’s compatibility notes or use Windows Update rather than forcing an unsupported driver.
