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\&.
