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

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
