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

Key Features

• FireWire controller support: Enables Windows to recognize and operate a compatible Ricoh IEEE 1394 host controller.
• OHCI compatibility: Uses the Open Host Controller Interface standard to manage communication with supported FireWire peripherals.
• Device connectivity: Provides the controller-level support needed for data transfers and peripheral detection. Some connected devices may also require their own drivers or software.
• Windows support: Driver options cover Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches your Windows version, system architecture, and hardware ID.

How to Install

1. Confirm your controller and Windows version. Open Device Manager and look under “IEEE 1394 Bus host controllers.” Check the Ricoh controller’s properties, including its hardware IDs, and confirm whether your Windows installation is 32-bit or 64-bit.

1. Download a compatible driver package. Select the Ricoh 1394 OHCI Compliant Host Controller driver intended for your operating system and hardware. Extract the files first if the download is compressed.

1. Install or update the driver. If the package includes an installer, follow its prompts. Otherwise, right-click the controller in Device Manager, choose the driver update option, and browse to the extracted driver folder. Menu wording varies between Windows versions.

1. Restart if prompted. Save any open work before restarting. Then return to Device Manager and confirm that the controller appears without a warning symbol.

1. Test a FireWire device. Connect a compatible peripheral with a suitable IEEE 1394 cable and check whether Windows or its associated application detects it. If it is not recognized, verify the cable, device power, and any additional software requirements.

Windows may already include a suitable Microsoft driver for this controller. If your FireWire equipment works correctly, a manual driver replacement may not be necessary.

Common Issues and Fixes

• Device not detected: Check the FireWire cable/port and confirm the attached camera, audio interface, or drive is powered. In Device Manager, look under IEEE 1394 host controllers for “1394 OHCI Compliant Host Controller”; if missing, scan for hardware changes and verify the PCI/PCIe card is seated and enabled in BIOS.
• Install fails or Code 10/28: This controller normally uses Microsoft’s built-in IEEE 1394 OHCI driver, not a separate Ricoh package. Remove any third-party 1394 driver, uninstall the device, reboot, and let Windows
