+ *  \section Sec_SummaryUSBTokens General USB Driver Related Tokens
  *  This section describes compile tokens which affect USB driver stack as a whole in the LUFA library.
  *
+ *  <b>NO_STREAM_CALLBACKS</b> - ( \ref Group_EndpointPacketManagement , \ref Group_PipePacketManagement )\n
+ *  Both the endpoint and the pipe driver code contains stream functions, allowing for arrays of data to be sent to or from the
+ *  host easily via a single function call (rather than complex routines worrying about sending full packets, waiting for the endpoint/
+ *  pipe to become ready, etc.). By default, these stream functions require a callback function which is executed after each byte processed,
+ *  allowing for early-aborts of stream transfers by the application. If callbacks are not required in an application, they can be removed
+ *  by defining this token, reducing the compiled binary size. When removed, the stream functions no longer accept a callback function as
+ *  a parameter.
+ *
+ *  <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>USE_STATIC_OPTIONS</b>=<i>x</i> - ( \ref Group_USBManagement ) \n
+ *  By default, the USB_Init() function accepts dynamic options at runtime to alter the library behaviour, including whether the USB pad
+ *  voltage regulator is enabled, and the device speed when in device mode. By defining this token to a mask comprised of the USB options
+ *  mask defines usually passed as the Options parameter to USB_Init(), the resulting compiled binary can be decreased in size by removing
+ *  the dynamic options code, and replacing it with the statically set options. When defined, the USB_Init() function no longer accepts an
+ *  Options parameter.
+ *
+ *  <b>USB_DEVICE_ONLY</b> - ( \ref Group_USBManagement ) \n
+ *  For the USB AVR models supporting both device and host USB modes, the USB_Init() function contains a Mode parameter which specifies the
+ *  mode the library should be initialized to. If only device mode is required, the code for USB host mode can be removed from the binary to
+ *  save space. When defined, the USB_Init() function no longer accepts a Mode parameter. This define is irrelevant on smaller USB AVRs which
+ *  do not support host mode.
+ *
+ *  <b>USB_HOST_ONLY</b> - ( \ref Group_USBManagement ) \n
+ *  Same as USB_DEVICE_ONLY, except the library is fixed to USB host mode rather than USB device mode. Not available on some USB AVR models.
+ *
+ *  <b>USB_STREAM_TIMEOUT_MS</b>=<i>x</i> - ( \ref Group_USBManagement ) \n
+ *  When endpoint and/or pipe stream functions are used, by default there is a timeout between each transfer which the connected device or host
+ *  must satisfy, or the stream function aborts the remaining data transfer. This token may be defined to a non-zero 16-bit value to set the timeout
+ *  period for stream transfers, specified in milliseconds. If not defined, the default value specified in LowLevel.h is used instead.
+ *
+ *  <b>NO_LIMITED_CONTROLLER_CONNECT</b> - ( \ref Group_Events ) \n
+ *  On the smaller USB AVRs, the USB controller lacks VBUS events to determine the physical connection state of the USB bus to a host. In lieu of
+ *  VBUS events, the library attempts to determine the connection state via the bus suspension and wake up events instead. This however may be
+ *  slightly inaccurate due to the possibility of the host suspending the bus while the device is still connected. If accurate connection status is
+ *  required, the VBUS line of the USB connector should be routed to an AVR pin to detect its level, so that the USB_DeviceState global
+ *  can be accurately set and the \ref EVENT_USB_Device_Connect() and \ref EVENT_USB_Device_Disconnect() events manually raised by the RAISE_EVENT macro.
+ *  When defined, this token disables the library's auto-detection of the connection state by the aforementioned suspension and wake up events.
