Simplistic. Speedy. Expansive. Complement your computer with added ports and style. Features A Polished Look - The solid aluminum body with rounded corners fits the ambience, staying sleek for years to come. Ultra miniature, free yourself from cable chaos and put your workspace back in order - all without taking up too much space. Intuitive Design - The provided hook and loop strip fixes the hub in place - under the monitor, beside the laptop or wherever seems best to you - and facilitates one-handed plugging and unplugging. Horizontally-positioned ports give a wider berth for over-sized USB connectors. Taken together, this is data access made as easy and intuitive as possible. SuperSpeed 4 - Don't deny your devices access to SuperSpeed ports. With transfer rates of up to 5Gbps, set aside less time for syncing and more time for work (or play). With 4 data terminals to choose from, forget about ever having to switch or unplug again. Compatibility Windows (32/64 bit) 10 / 8.1 / 8 / 7 / Vista / XP, Mac OS X 10.6 to 10.9, Linux 2.6.14 or above. Mac OS X Lion 10.7.4 users should upgrade to Mountain Lion 10.8.2 or later to avoid unstable connections. 2.4GHz wireless devices, MIDI devices and some USB 3.0 devices may not be supported. Try using the host port or a USB 2.0 connection. For a stable connection, don't use this hub with high power-consumption devices, such as external hard drives. The hub will sync but not charge tablets and other devices which require a higher power input.
