There really isn't much to installing the DUB-H4. Start by plugging the provided cable's USB Type B Connector into the back of the hub. Next, connect the AC adapter to the hub and plug the adapter into a live receptacle. Finish by plugging the provided cable's Type A connector into a USB port. If you want the high-speed benefits of USB 2.0, make sure you attach the hub to a USB 2.0 port. Once you have made the connection, your computer will automatically detect and install the DUB-H4 unit.
