NAME
       config_ep_by_speed - configures the given endpoint according to gadget speed.

SYNOPSIS
       int config_ep_by_speed(struct usb_gadget * g, struct usb_function * f, struct usb_ep * _ep);

ARGUMENTS
       g
	   pointer to the gadget

       f
	   usb function

       _ep

       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.

NOTE
       the supplied function should hold all the descriptors for supported speeds
