Introduction

U31-PCIE2XG321 is a 2-port USB 3.1 Gen-II (10Gbps) to PCI Express x4 (x2 mode) Gen 3 Host Card.
U31-PCIE2XG321 is designed with the new generation Universal Serial Bus XHCI host controller, bridging PCI Express to USB3.1 Gen-II, compliant with USB 3.1 Specification Revision 1.0 and Intel eXtensible Hot Controller Interface specification revision 1.1,.

U31-PCIE2XG321 (Rev 1.1.0) also supports the new feature of USB 3.1 Gen2, named Multiple INs to achieve fully utilization rate of 10Gbps data rate, tacking advantage of the available bandwidth of USB 3.1 Gen2 bus.
U31-PCIE2XG321 supports two USB 3.1 Gen-II (10Gbps) ports and perform trusting high speed bandwidth with PCIe Gen-III x2 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.
