NAME

       usb_ia - USB interface association driver

SYNOPSIS

       interface association@unit-address

DESCRIPTION

       The  usb_ia driver is a USBA (Solaris Universal Serial Bus Architecture)-compliant nexus driver that binds to a device's interface associa-
       tion nodes when no vendor or class specific driver is available. To do this, usb_ia 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 usb_mid(7D) and all ugen(7D) interfaces are exported by
       usb_mid(7D). (Note: attempting to export ugen(7D) interfaces using usb_ia is prohibited.)
