In all previous patches you set both dir_in and dir_out to true for ep0
but in this patch you don't do this. Is there some reason for this or
it's just a mistake?


Most of UDC drivers we have single instance of ep0 for both directions, but this one has two separate unidirectional ep0in and ep0out.

          /* need to set ep->ep.maxpacket and set Default
