+ * <b>FAST_STREAM_TRANSFERS</b> - ( \ref Group_EndpointPacketManagement , \ref Group_PipePacketManagement )\n
+ * By default, streams are transferred internally via a loop, sending or receiving one byte per iteration before checking for a bank full
+ * or empty condition. This allows for multiple stream functions to be chained together easily, as there are no alignment issues. However,
+ * this can lead to heavy performance penalties in applications where large streams are used frequently. When this compile time option is
+ * used, bytes are sent or recevied in groups of 8 bytes at a time increasing performance at the expense of a larger flash memory consumption
+ * due to the extra code required to deal with byte alignment.

* <b>USB_HOST_TIMEOUT_MS</b> - ( \ref Group_Host ) \n
* When a control transfer is initiated in host mode to an attached device, a timeout is used to abort the transfer if the attached
* device fails to respond within the timeout period. This token may be defined to a non-zero 16-bit value to set the timeout period for
