    234  * A session is something inside what any communication occurs.
    235  * It is expected that sessions would be started right before the transfer
    236  * and ended - see usb_pipe_end_session() - after the last
    237  * transfer.
    238  * The reason for this is that session actually opens some communication
    239  * channel to the host controller (or to the physical hardware if you
    240  * wish) and thus it involves acquiring kernel resources.
    241  * Since they are limited, sessions shall not be longer than strictly
    242  * necessary.
    243  *
    244  * @deprecated
    245  * Obsoleted with introduction of usb_pipe_start_long_transfer
