Original Press Release:

USB Hubs Put 500 mA on Each Port

USB hubs are easy to find-but not if you need a full 500 mA from each downstream port for such industrial applications as data acquisition and digital I/O. That's why CyberResearch® offers a full 500 mA per port plus surge protection on both its four-port USB 2.0 hubs and its seven-port USB 1.1 hubs.

The USBH 3204 hub from CyberResearch, Inc. offers the high speed of USB 2.0, plus connectivity to any existing USB 1.0 or 1.1 devices. Connectors are fully compatible with all three specifications, so users don't need cable adapters.

Users who need more downstream ports but don't require the speed of USB 2.0 can specify the CyberResearch USBH 3117, with seven downstream ports.

Both hubs come with drivers, USB cables, and power supplies. They can be daisy-chained to connect up to 127 USB devices-and they're stackable, so they don't take up much space.

Both also offer the advantages of USB plug-and-play and hot-swap features. Users just load up the free drivers, connect their hubs, and plug in their peripherals. They never have to open up or even reboot their PCs.

In addition to USB hubs-now shipping from stock-CyberResearch, Inc., also offers industrial-grade panel-mount, rack-mount, and desktop PCs, as well as data-acquisition and motion-control systems. For more information on our products, call Joe Tetreault at 800-341-2525, or visit
