.SH "NAME"
usb_composite_probe \- register a composite driver
.SH "SYNOPSIS"

.BI "int usb_composite_probe(struct\ usb_composite_driver\ *\ " "driver" ");"
.SH "ARGUMENTS"

the driver to register
.RE
.SH "CONTEXT"
.PP
single threaded during gadget setup
.SH "DESCRIPTION"
.PP
This function is used to register drivers using the composite driver framework\&. The return value is zero, or a negative errno value\&. Those values normally come from the driver\*(Aqs
\fIbind\fR
method, which does all the work of setting up the driver to match the hardware\&.
.PP
On successful return, the gadget is ready to respond to requests from the host, unless one of its components invokes
\fBusb_gadget_disconnect\fR
while it was binding\&. That would usually be done in order to wait for some userspace participation\&.
