NAME
     usba  - Solaris USB Architecture (USBA)

DESCRIPTION
     USB provides a low-cost means for attaching peripheral  dev-
     ices,  including  mass-storage devices, keyboards, mice, and
     printers, to a system. For complete information on  USB,  go
     to the USB website at http://www.usb.org.

     USB supports 126 hot-pluggable USB devices per USB bus.  The
     maximum data transfer rate is 12 Mbits per second (Mbps).

     USB  adheres to the Universal Serial Bus  1.1  specification
     and  provides  a  transport  layer abstraction to USB client
     drivers.
