Adding connectivity to your computer has never been easier. IOGEAR's GIC251U card adds 5 USB 2.0 ports in a snap. Four of the ports are external for printers, cameras and myriad other devices. There is an internal port so you can hook up a front panel card reader or other device. It's also a great place to put your USB to Bluetooth adapter. The PCI 2.2 interface lets you use the card in a wide range of computers. Today's operating systems will easily find the card and set everything up so you will be back up and running in no time.
