Ativa USB 2.0 4-Port Hub, item 900-447, new in the original unopened package. It connects up to four USB devices through one USB port on your computer, with side-loading ports and a short attached cable that clips neatly to the hub for travel. It's bus-powered, so no power adapter is needed, and it has a durable rubberized black finish. The package lists compatibility with Windows 8, 7, Vista, and XP, and Mac OS X 10.0 and above. It's great for laptops, desk setups, or adding extra ports for keyboards, mice, flash drives, and chargers. The package has light shelf wear and scuffing on the clear plastic, as pictured. Please see all photos, which are part of the description.
