17       config
18           the configuration, with bConfigurationValue assigned
19
20       bind

22

CONTEXT

24       single threaded during gadget setup
25

DESCRIPTION

27       One of the main tasks of a composite bind() routine is to add each of
28       the configurations it supports, using this routine.
29
30       This function returns the value of the configuration's bind(), which is
31       zero for success else a negative errno value. Binding configurations
32       assigns global resources including string IDs, and per-configuration
33       resources such as interface IDs and endpoints.
