Product Description 

The SW-USB-H4 is a 4-port Universal Serial Bus USB hub that allows a user to connect up to four USB peripherals or devices to their USB ready PC or iMac. It provides an out of the box industry standard Bus. The SW-USB-H4 is targeted at PC and iMac users that are expanding the number of USB ports on their system. 

Seamless Connections 

The SW-USB-H4 is designed to provide quick and easy access to the four type "A" downstream ports for connecting peripherals with USB support, other USB hubs and devices. A single type "B" upstream port is provided for connecting to the host computer, or another USB hub. Configured directly by the operating system, the SW-USB-H4 operates seamlessly with both Microsoft's OpenHCI and Intel's UniversalHCI.

Low and High Speeds Supported with Data Buffering

As a standard USB hub it buffers USB data from any attached peripherals or devices in compliance with USB Specification version 1.1 to provide an invisible extension of the USB bus. Supporting both low speed 1.5 Mbps devices and high speed 12 Mbps devices, each port creates a bridge between the peripheral and host computer.

Flexible Power, Flexible Solution 

Power for the SW-USB-H4 can be provided directly from the USB bus for connection of up to four low-powered USB devices. When using AC adapter in self-powered mode, the SW-USB-H4 can support up to four high-powered USB devices or up to four downstream bus-powered USB hubs.
