NAME
     usb_ia - USB Interface Association Driver

SYNOPSIS
     Interface Association Node Name@unit-address

DESCRIPTION
     The usb_ia driver is a USBA (Solaris  Universal  Serial  Bus
     Architecture) compliant nexus driver that binds to Interface
     Association nodes of a device if no vendor or class specific
     driver is available. The usb_ia driver creates nodes for the
     internal interfaces and attempts to  bind drivers to each of
     child interfaces.

     Interface association nodes's parent is device node which is
     created by usb_mid(7D). ugen(7D) interfaces are not  allowed
     to be exported in usb_ia since usb_mid(7D) has exported  all
     the ugen(7D) interfaces.
