USB_COMPOSITE_PROBE(9)                Kernel Mode Gadget API               USB_COMPOSITE_PROBE(9)



NAME
       usb_composite_probe - register a composite driver

SYNOPSIS
       int usb_composite_probe(struct usb_composite_driver * driver);

ARGUMENTS
       driver
           the driver to register

CONTEXT
       single threaded during gadget setup

DESCRIPTION
       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's
       bind method, which does all the work of setting up the driver to match the hardware.

       On successful return, the gadget is ready to respond to requests from the host, unless one
       of its components invokes usb_gadget_disconnect while it was binding. That would usually
       be done in order to wait for some userspace participation.
