usb_ia \- USB interface association driver

.SH DESCRIPTION
.sp
.LP
The \fBusb_ia\fR 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, \fBusb_ia\fR creates nodes for the internal interfaces and then attempts
to bind drivers to each child interface.
.sp
.LP
Each interface association node has a parent device node that is created by
\fBusb_mid\fR(7D) and all \fBugen\fR(7D) interfaces are exported by
\fBusb_mid\fR(7D). (Note: attempting to export \fBugen\fR(7D) interfaces using
\fBusb_ia\fR is prohibited.)
