- int config_ep_by_speed(struct usb_gadget * g, struct usb_function * f, struct usb_ep * _ep);
- pointer to the gadget
- usb function
- the endpoint to configure
error code, 0 on success
This function chooses the right descriptors for a given endpoint according to gadget speed and saves it in the endpoint desc field. If the endpoint already has a descriptor assigned to it - overwrites it with currently corresponding descriptor. The endpoint maxpacket field is updated according to the chosen descriptor.
the supplied function should hold all the descriptors for supported speeds
