The Ricoh 1394 OHCI Compliant Host Controller driver enables Windows to communicate with the Ricoh IEEE 1394 (FireWire) controller in your computer. This Microsoft-provided driver supports the connection between the controller and compatible FireWire equipment, such as digital camcorders, external storage devices, and audio interfaces.

Key Features

• FireWire controller support: Allows Windows to recognize and use the Ricoh 1394 OHCI Compliant Host Controller for IEEE 1394 connections.
• OHCI compatibility: Provides the standard Open Host Controller Interface support used to manage communication with compatible FireWire devices.
• Data transfer support: Enables the controller to handle transfers between your PC and connected equipment. Actual performance depends on the controller, cable, peripheral, and software.
• Windows driver integration: Supports installation and management through Windows Device Manager. Driver selection varies by operating system, including Windows 10, 8.1, 7, Vista, and XP.

How to Install

1. Check your system and controller. Confirm your Windows version and whether it is 32-bit or 64-bit. Open Device Manager and look under “IEEE 1394 Bus host controllers” for the Ricoh controller. If it appears as an unknown device, check its hardware IDs before choosing a download.

1. Select a compatible driver package. Download the Microsoft driver offered for your exact Windows version and system architecture. Do not assume that a package intended for Windows XP or Vista will also work with Windows 7, 8.1, or 10.

1. Extract the download if necessary. If the package is compressed, extract it to an accessible folder. If it includes an installer, run it and follow the prompts. Otherwise, install the driver through Device Manager.

1. Update the controller driver. Right-click the controller in Device Manager and choose the driver update option. Select the option to browse your computer or specify a location, then point Windows to the extracted driver folder. The wording differs between Windows versions.

1. Restart and test the connection. Restart if prompted, then confirm that the controller appears without a warning icon. Connect your FireWire device and test it with the appropriate application.

This driver operates the host controller; some connected peripherals also require their own drivers or software. If Windows already recognizes the controller and your equipment works correctly, a manual driver replacement may not be necessary.

Common Issues and Fixes

• Install fails or Code 10/28: Windows may reject an unsigned or outdated 1394 driver. Remove the device in Device Manager (enable Show hidden devices), reboot, and let Windows install the Microsoft 1394 OHCI driver. Use a Ricoh/OEM package only if it explicitly supports your Windows version.
