  • Dual USB 2.0 Controllers (Each has one EHCI and one OHCI, total are two EHCI and two OHCI)
  • Compliant with Universal Serial Bus Specification Revision 2.0 (data rate: 1.5/12/480 Mbps)
  • Six USB Ports (Four External + Two Internal)
  • Supports hyper-speed transfer mode.
  • Good performance for Read-intensive applications
Introduction

U2-PCIE10 is Dual Channel USB 2.0 to PCI Express Host Adapter

U2-PCIE10 is designed with two key components.

  • PCI Express to PCI Bus Translation Bridge.
  • PCI multi-function device consists of one OHCI host controller core for full-/low-speed signaling and one EHCI host controller core for high-speed signaling.

The PCI Express to PCI local bus translation bridge takes advantages of the 2.5 Gb/s burst rate of 1-lane PCI Express bus and the PCI bus interface is connected to two PCI multi-function devices are integrated at the Secondary Bus to provide more connectivity and performance.

U2-PCIE10 complies with USB Revision 2.0 and OHCI (Open Host Controller Interface) specification for full/low-speed signaling, and Intel's EHCI (Enhanced Host Controller Interface) specification for high-speed signaling which can work up to 480Mbps.

U2-PCIE10 supports hyper-speed transfer mode for asynchronous transfer in high-speed mode, and it can greatly improve data transfer rate for high-speed devices supporting bulk transfer, such as USB storage, scanner, printer, etc.
