+ * An important difference between packet and transaction modes is that there
+ * is a dedicated endpoint buffer in packet mode while in transaction mode
+ * the application has to specify its own buffer for duration of the whole
+ * transfer.<br>
+ * Packet buffers cannot be accessed directly by the application because those
+ * could not be necessarily memory mapped, a buffer could be a FIFO or some
+ * other kind of memory accessible in a special way depending on the
+ * underlying hardware architecture, the functions @p usbReadPacketI() and
+ * @p usbWritePacketI() allow to access packet buffers in an abstract way.

  * The USB driver uses callbacks in order to interact with the application.
