V2U31-PCIE1XG322-13

V2U31-PCIE1XG322-13 is a 2-port USB 3.1 Gen 2 (10 Gbps) to PCI Express ×1 Gen 3 host card. It features the latest Universal Serial Bus XHCI host controller, converting PCIe to USB 3.1 Gen 2 (10 Gbps), fully compliant with USB 3.1 Specification Rev 1.0 and Intel eXtensible Host Controller Interface (xHCI) Spec Rev 1.1.
The V2U31-PCIE1XG322-13 supports the USB 3.1 Gen 2 “Multiple INs” capability, enabling full utilization of the 10 Gbps bandwidth. It provides two USB 3.1 Gen 2 ports, delivers reliable high-speed throughput over the PCIe ×1 Gen 3 interface, and remains backward-compatible with legacy USB devices. The card also supports UASP (USB Attached SCSI Protocol) Rev 1.0 and offers xHCI debug functionality.
Driver support includes a proprietary driver for Windows 7, and inbox drivers for Windows 8.0, 8.1, 10, as well as for various Linux kernels.
