.SH "MEMBERS"
.TP
\fBep0\fR
Endpoint zero, used when reading or writing responses to
driver \fBsetup\fR requests

.TP
\fBname\fR
Identifies the controller hardware type.  Used in diagnostics
and sometimes configuration.
.SH "DESCRIPTION"
.PP
Gadgets have a mostly-portable ``gadget driver'' implementing device
functions, handling all usb configurations and interfaces.  They
also have a hardware-specific driver (accessed through ops vectors),
which insulates the gadget driver from hardware details and packages
the hardware endpoints through generic i/o queues.
.PP
Except for the driver data, all fields in this structure are
read-only to the gadget driver.  That driver data is part of the
``driver model'' infrastructure in 2.5 (and later) kernels, and for
earlier systems is grouped in a similar structure that's not known
to the rest of the kernel.
