* \section Sec_SummaryUSBTokens USB Driver Related Tokens
* \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.

* Some applications prefer to not call the USB_USBTask() management task reguarly while in device mode, as it can complicate code significantly.
* Instead, when device mode is used this token can be passed to the library via the -D switch to allow the library to manage the USB control
* endpoint entirely via USB controller interrupts asynchronously to the user application.
*
* <b>FAST_STREAM_TRANSFERS</b> - ( \ref Group_EndpointPacketManagement , \ref Group_PipePacketManagement )\n

* Many devices do not require the use of the Remote Wakeup features of USB, used to wake up the USB host when suspended. On these devices,
* the code required to manage device Remote Wakeup can be disabled by defining this token and passing it to the library via the -D switch.
*
* <b>NO_DEVICE_SELF_POWER</b> - (\ref Group_Device ) \n
* USB devices may be bus powered, self powered, or a combination of both. When a device can be both bus powered and self powered, the host may
* query the device to determine the current power source, via \ref USB_CurrentlySelfPowered. For solely bus powered devices, this global and the
* code required to manage it may be disabled by passing this token to the library via the -D switch.
