Introduction

U31-PCIE1XG322-13 is a 2-port USB 3.1 Gen 2 (10Gbps) to PCI Express x1 Gen 3 Host Card.
U31-PCIE1XG322-13 is designed with the new generation Universal Serial Bus XHCI host controller, bridging PCI Express to USB 3.1 Gen 2 (10Gbps), compliant with USB 3.1 Specification Revision 1.0 and Intel eXtensible Hot Controller Interface specification revision 1.1.
U31-PCIE1XG322-13 also supports the new feature of USB 3.1 Gen 2, named Multiple INs to achieve fully utilization rate of 10Gbps data rate, tacking advantage of the available bandwidth of USB 3.1 Gen 2 bus.
U31-PCIE1XG322-13 supports two USB 3.1 Gen 2 (10Gbps) ports and perform trusting high speed bandwidth with PCIe x1 Gen 3 supporting. It also supports backward compatible with legacy USB function and devices, compliant with UASP (USB Attach SCSI Protocol) Revision 1.0, supporting the XHCI debug capability.

U31-PCIE1XG322-13 supports the proprietary driver for Windows 7 and inbox driver for Windows 8.0, Windows 8.1, Windows 10 and various Linux Kernels.
