Using Fresco Logic FL1100 USB 3.0 Cards on Mac Pro 5,1
The Fresco Logic FL1100 chipset is one of the most compatible USB 3.0 options for the Mac Pro 5,1 because it has native driver support in macOS and is supported by the OpenCore environment.
Technical Implementation:
- Native Support: Unlike other chipsets, the FL1100 does not require additional kexts in Monterey, Ventura, or Sonoma. It works out of the box.
- Boot Support: Most FL1100 cards support Legacy USB, meaning you can use them to navigate the OpenCore picker and Apple's native boot manager.
- Power Considerations: While the card provides up to 3A, ensure you aren't overloading the PCIe bus if you also have a power-hungry GPU like an RX 580 or Vega 56.
- Installation: Simply plug the card into any available PCIe slot (Slot 3 or 4 are ideal). No software configuration is needed.
Expert Tip: This card is a superior alternative to using a USB hub for mouse/keyboard during installation, as it provides stable 5Gbps speeds for the installer drive as well.
