usb_add_config — add a configuration to a device.
int usb_add_config ( | struct usb_composite_dev * cdev, |
struct usb_configuration * config); |
One of the main tasks of a composite driver's 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.
