The UPort 200 series products are high grade USB hubs available in 4 or 7 port variants. The products are USB-IF (USB Implementers Forum) approved and have ESD level 4 protection to defend against unwanted surges.
The hubs are designed to provide true USB 2.0 high speed (480Mbps) throughput per port so if you have a professional application and are experiencing problems with a low grade USB hub, be sure to give the UPort series a try.
