USB_IA(7D)USB_IA(7D)NAMEusb_ia - USB interface association driver
SYNOPSIS
interface association@unit-address
DESCRIPTION
The usb_ia driver is a USBA (Solaris Universal Serial Bus Architec‐
ture)-compliant nexus driver that binds to a device's interface associ‐
ation 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 cre‐
ated 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.)
