USB Hubs
Four-port and seven-port hubs are USB 2.0-compliant, providing 480 Mbps  data rate to the host and are backward-compatible with USB 1.1 and 1.0  devices. Each includes a wall-mount ac adapter that supplies 500 mA to  each attached USB peripheral. Both hubs are housed in rugged plastic  enclosures. The hubs are supported in Windows, Linux and other USB-aware  operating systems.
