5.2 Software Installation (Drivers)
The ORICO PFU3-2P card typically uses standard USB 3.0 host controller drivers. Driver installation varies by operating system:
- Windows: For most modern Windows operating systems (Windows 8, 10, 11), the card should be plug-and-play, with drivers automatically installed by the system. If drivers are not automatically detected, check Windows Update or the ORICO official weblloc web per a descàrregues de controladors específics.
- macOS: Drivers for macOS are natively included in OS X Mountain Lion (10.8.2) and later versions as part of the operating system updates. For older versions like Snow Leopard or Lion, third-party drivers may be required. Please consult ORICO's official support resources for compatibility with specific macOS versions, especially newer releases like OS X 10.11 (El Capitan) and beyond, as compatibility can vary.
- Linux: Most modern Linux distributions include native support for USB 3.0 host controllers. If issues arise, consult your distribution's documentation or community forums.
