NAME

6       usb_ia - USB interface association driver
7

SYNOPSIS

9       interface association@unit-address
10
11

DESCRIPTION

13       The  usb_ia  driver  is  a USBA (Solaris Universal Serial Bus Architec‐
14       ture)-compliant nexus driver that binds to a device's interface associ‐
15       ation nodes when no vendor or class specific driver is available. To do
16       this, usb_ia  creates  nodes  for  the  internal  interfaces  and  then
17       attempts to bind drivers to each child interface.
18
19
20       Each  interface  association node has a parent device node that is cre‐
21       ated by  usb_mid(7D)  and  all  ugen(7D)  interfaces  are  exported  by
22       usb_mid(7D).  (Note:  attempting  to  export  ugen(7D) interfaces using
23       usb_ia is prohibited.)
