Introduction

U32-PCIE4XG321 is a 1-port USB 3.2 Gen 2x2 (20Gbps) to PCIe x4 Gen 3 Host Card.
U32-PCIE4XG321 is designed with the new generation Universal Serial Bus XHCI host controller, bridging PCI Express to USB 3.2 20Gbps, compliant with USB 3.2 Specification Revision 1.0 and Intel eXtensible Hot Controller Interface specification revision 1.1.

U32-PCIE4XG321 supports one USB 3.2 20Gbps port and perform trusting high speed bandwidth with PCIe Gen 3 x4 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.

U32-PCIE4XG321  also supports the function of Multiple INs to achieve fully utilization rate of 20Gbps data rate, taking advantage of the available bandwidth of USB3.2 Gen2 x2 bus..
