Entrega HUB-4U2S1P Multi Function HUB 7-Port

Amazon.com Entrega Technologies' multifunction USB hub endows a USB-enabled notebook or desktop with four additional USB ports, two serial ports, and 1 parallel-printer port--all in one convenient unit. Desktop users enjoy additional expansion capabilities without the hassle of hard-to-reach ports in the back of the PC. Installation is simple, and there's no need to open the computer. And, with Entrega USB technology, serial devices and parallel printers that already work on the system will be automatically configured. The hub features individually switched ports so that if a device fails, the rest will continue operating. And auto-recovery technology ensures that if a port shuts down, it will automatically reset itself when a new device is plugged in. Included with the hub are a 2-meter USB cable, a 3.7-amp AC power supply, an instruction book, and a full three-year "fix it or replace it" warranty.
