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.)
