The DUB-H4 is a 4-port Universal Serial Bus USB 2.0 hub that allows you to connect up to 4 USB 2.0 peripherals and devices to your USB 2.0 ready PC or iMac. Providing an out of the box industry standard bus, this pocket-sized device expands your PC and Mac by adding 4 USB 2.0 ports to your system.A single Type B upstream port is provided to connect to the host computer, or another USB hub. Configured directly by the operating system, the DUB-H4 operates seamlessly with both Microsoft's OpenHCI, Intel's Universal HCI and USB 2.0 new generation specification EHCI. As a standard USB hub, it buffers USB data from any attached peripherals or devices in compliance with USB specification versions 1.1 and 2.0 to provide an invisible extension of the USB bus. Supporting both low-speed 1.5Mbps devices, full-speed 12Mbps devices and high-speed 480Mbps, each port creates a bridge between the peripheral and host computer.
