The OHCI-konformer Ricoh 1394-Hostcontroller driver enables Windows to communicate with a Ricoh IEEE 1394 controller, commonly known as a FireWire controller. This Microsoft-provided driver supports the connection between the host 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 manage the Ricoh OHCI-compliant IEEE 1394 host controller.
• Peripheral communication: Provides the host-controller support needed for data transfers with compatible FireWire devices. Some equipment may also require its own drivers or software.
• Windows integration: Works with Windows device-management tools, letting you check controller status, update the driver, or roll back an update through Device Manager.
• Support for multiple Windows versions: Driver options cover Windows 10, 8.1, 7, Vista, and XP. Select a package that matches your operating system, hardware, and 32-bit or 64-bit architecture.

How to Install

1. Confirm the controller and operating system. Open Device Manager and locate the controller under “IEEE 1394 Bus host controllers.” If it appears as an unknown device, check its hardware IDs in Properties to confirm that the selected driver applies. Verify your Windows version and system architecture before downloading.

1. Download a matching driver package. Choose the Microsoft driver intended for your controller and Windows edition. Avoid installing a package simply because its name includes “1394”; compatibility with the actual controller matters.

1. Prepare the files. Extract the download if it is compressed. Save any open work and, where available, create a restore point before changing the installed driver.

1. Install or update the driver. Run the included installer if one is provided. Otherwise, right-click the controller in Device Manager, select 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, then check that the controller appears without a warning icon. Connect your FireWire device and test it with the appropriate application.

If Windows already recognizes the controller and your equipment works correctly, a manual update may not be necessary. For connection problems, also check the FireWire cable, device power, and any peripheral-specific software requirements.
