What is the PCI OHCI Standard IEEE 1394 Host Controller Driver?

The PCI OHCI Standard IEEE 1394 Host Controller driver is a software component that enables communication between your computer's operating system (like Windows) and devices that use the IEEE 1394 standard, also known as FireWire. This standard is commonly used for high-speed data transfer, especially for devices like digital cameras, external hard drives, audio/video equipment, and other peripherals that require fast, reliable data transfer.

• OHCI (Open Host Controller Interface) is a specification for FireWire that defines how the host controller communicates with IEEE 1394 devices.
• The PCI in the name refers to the type of bus interface (Peripheral Component Interconnect), indicating the controller is connected via a PCI slot on the motherboard.

In short, this driver allows your computer to properly detect and interact with FireWire devices.
