Nowadays anything can be a USB hub, from sushi shaped, to tiki trees, to cup warmers you name it they make it. Here is another one. A 4 port hub USB 2.0 compatible, has a transfer speed of up to 480 Mbps, requires no adapter, opens letters automatically (when the envelop touches the spring slice), it’s USB powered or 3AA batteries, and it’s compatible with windows Me/98/2000/xp, [I don’t know about vista]. The clock features a 12/24 hour mode switch, displays hour, minute, second, month and day. Did I mention that this gadget requires no software? Just plug and play.
