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(4D) and all ugen(4D) interfaces are exported by usb_mid(4D).
(Note: attempting to export ugen(4D) interfaces using usb_ia is
prohibited.)
