USB_ADD_CONFIG(9)                     Kernel Mode Gadget API                    USB_ADD_CONFIG(9)



NAME
       usb_add_config - add a configuration to a device.

SYNOPSIS
       int usb_add_config(struct usb_composite_dev * cdev, struct usb_configuration * config,
                          int (*bind) (struct usb_configuration *));

ARGUMENTS
       cdev
           wraps the USB gadget

       config
           the configuration, with bConfigurationValue assigned

       bind
           the configuration's bind function

CONTEXT
       single threaded during gadget setup

DESCRIPTION
       One of the main tasks of a composite bind() routine is to add each of the configurations
       it supports, using this routine.

       This function returns the value of the configuration's bind(), which is zero for success
       else a negative errno value. Binding configurations assigns global resources including
       string IDs, and per-configuration resources such as interface IDs and endpoints.
