Introduction

U3-PCIE1XG201 is a USB 3.0 to PCI Express Gen2 Host Bus Adapter.

The U3-PCIE1XG201 complies with Universal Serial Bus 3.0 Specification, and Intel’s eXtensible Host Controller Interface (xHCI).

The U3-PCIE1XG201 uses a PCI Express bus interface, and it is applicable for PCI Express solutions with host PC systems.

The U3-PCIE1XG201 supports data transfer up to 5 Gbps when connecting to USB 3.0 compliant peripherals, while maintaining compatibility with existing USB peripheral devices.

Computer Platform

Computer with PCI Express slot (x1, x4, x8, x16)

Note:
For the best performance (5.0 Gbps), U3-PCIE1XG201 should be installed in a PCIe Gen 2 compliant slot in the host computer.  Most computers have PCIe Gen 2 (5.0 Gbps) throughput on x8 or x16 slots.
A PCIe Gen 1 compliant slot reaches up to 2.5 Gbps throughput

Operating System Requirements

• Windows XP, Windows Vista, Windows 7
• USB 3.0 Host Controller Driver Kit (x86 and x64)
• For Windows XP, Vista and 7
