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.)
