6 LSI60800 PCI to USB Host Adapter

4.1 Cabling

The LSI60800 PCI to USB Host Adapter supports type A cable

connectors only.

The USB specification provides for two types of cables. For full-speed

devices like scanners, cameras, printers, and speakers, a full-speed

cable must be used. For low-speed devices like keyboards, mice,

joysticks, and other game devices, a sub-channel or low-speed cable can

be used.

4.2 Hubs

The USB specification supports two types of hubs; cable-powered and

self-powered. A self-powered hub can support all USB devices,

independent of the USB device power requirements. A cable-powered

hub can support only devices which use 100 mA or less. Also, a hub

must be connected using only a high-speed cable.
