 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
association 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.)
