Seamless Connections
The DUB-H4 is designed to provide quick and easy access to the 4 Type A downstream ports to connect to peripherals with USB 2.0 support, other USB hubs and devices. 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 UniversalHCI and
USB 2.0 new generation specification EHCI.

Low, Full 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 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.

Feature-Rich and Easy to Use
Diagnostic LED's are mounted on the device to provide the user with power state and port status. The DUB-H4 is packaged with a 6-feet USB 2.0 A-to-B cable, and a DC 5V/2.5A external AC power supply. Feature-Rich and Easy to Use
