This item is smaller than a deck of cards and has 4 active USB 2 ports. Revain's description says it is a USB 1.1 device. According to the literature, it is a USB 2 device. I needed a self-powered USB 1.1 compatible hub for my laptop. My system shows a hub running faster over a USB 2 port, but it works fine on my laptop. I bought this USB hub because TrippLite has a very good reputation and makes great products. I was not disappointed.
