Fresco Logic XHCI USB 3.0 Controller FL1100 Series Drivers (Windows 10/8/7/Vista/XP)

The Fresco Logic FL1100 chipset is commonly found in a variety of USB expansion solutions, both onboard and add-in. It is often integrated directly into motherboards to provide additional USB 3.0 ports, especially on systems where the native chipset offers limited connectivity. You may also encounter the FL1100 on external PCIe expansion cards, similar to the one shown in the image to the left, allowing desktops to add high-speed USB 3.0 support. In some cases, the chipset is used in specialized industrial, workstation, or embedded systems that require reliable USB performance. Its widespread adoption is due to stable drivers, broad operating system support, and consistent transfer speeds across connected USB devices.
