- * A newly configured pipe is frozen by default, and must be unfrozen before use via the \ref Pipe_Unfreeze()
- * before being used. Pipes should be kept frozen unless waiting for data from a device while in IN mode, or
- * sending data to the device in OUT mode. IN type pipes are also automatically configured to accept infinite
- * numbers of IN requests without automatic freezing - this can be overridden by a call to
- * \ref Pipe_SetFiniteINRequests().
- *
- * \param[in] Number Pipe number to configure. This must be more than 0 and less than \ref PIPE_TOTAL_PIPES.
- *
- * \param[in] Type Type of pipe to configure, an \c EP_TYPE_* mask. Not all pipe types are available on Low
- * Speed USB devices - refer to the USB 2.0 specification.
- *
- * \param[in] Token Pipe data token, either \ref PIPE_TOKEN_SETUP, \ref PIPE_TOKEN_OUT or \ref PIPE_TOKEN_IN.
- * All pipes (except Control type) are unidirectional - data may only be read from or
- * written to the pipe bank based on its direction, not both.
- *
- * \param[in] EndpointNumber Endpoint index within the attached device that the pipe should interface to.
- *
- * \param[in] Size Size of the pipe's bank, where packets are stored before they are transmitted to
- * the USB device, or after they have been received from the USB device (depending on
- * the pipe's data direction). The bank size must indicate the maximum packet size that
- * the pipe can handle.
- *
- * \param[in] Banks Number of banks to use for the pipe being configured, a \c PIPE_BANK_* mask. More banks
- * uses more USB DPRAM, but offers better performance. Isochronous type pipes <b>must</b>
- * have at least two banks.
- *
- * \note When the \c ORDERED_EP_CONFIG compile time option is used, Pipes <b>must</b> be configured in ascending order,
- * or bank corruption will occur.
- * \n\n
- *
- * \note Certain models of USB AVR's pipes may have different maximum packet sizes based on the pipe's
- * index - refer to the chosen USB AVR's datasheet to determine the maximum bank size for each pipe.
- * \n\n
- *
- * \note The default control pipe should not be manually configured by the user application, as it is
- * automatically configured by the library internally.
- * \n\n
- *
- * \note This routine will automatically select the specified pipe upon success. Upon failure, the pipe which
- * failed to reconfigure correctly will be selected.
