Tripp Lite U222-007-R 7-Port USB 2.0 Hub
This rather unassuming USB hub is one of the most popular models on the market. It has seven USB 2.0 ports that are backwards compatible to work with USB 1.1 specifications. Five of them are located on one side of the hub along with the power and upstream connections, while the other two ports are on the other side of the device. One great feature of this model is you can easily set it up lying on its side, but there's also a stand so this pick can be positioned upright in a vertical configuration.
This USB hub supports all major operating systems which makes it easy to use with just about any setup and all of the ports are hot-swappable so you can quickly switch out devices as needed. While it doesn’t have any options for expansion if you need additional connections, it’s a perfect choice if you just need a seven-port USB 2.0 hub.
