NAME
     usbia - USB interface association driver

SYNOPSIS
     interface association@unit-address


DESCRIPTION
     The usbia driver is a USBA (Solaris  Universal  Serial  Bus
     Architecture)-compliant   nexus   driver  that  binds  to  a
     device's interface association nodes when no vendor or class
     specific  driver  is  available.  To do this, usbia creates
     nodes for the internal interfaces and then attempts to  bind
     drivers to each child interface.


     Each interface association node has  a  parent  device  node
     that  is  created by usbmid(7D) and all ugen(7D) interfaces
     are exported by usbmid(7D).  (Note:  attempting  to  export
     ugen(7D) interfaces using usbia is prohibited.)
