* Some AVR models contain a unique serial number which can be used as the device serial number, while in device mode. This allows
* the host to uniquely identify the device regardless of if it is moved between USB ports on the same computer, allowing allocated
* resources (such as drivers, COM Port number allocations) to be preserved. This is not needed in many apps, and so the code that
* performs this task can be disabled by defining this option and passing it to the compiler via the -D switch.

* <b>FIXED_CONTROL_ENDPOINT_SIZE</b>=<i>x</i> - ( \ref Group_EndpointManagement ) \n
* <b>FIXED_CONTROL_ENDPOINT_SIZE</b>=<i>x</i> - (\ref Group_EndpointManagement) - <i>All Architectures</i> \n
* By default, the library determines the size of the control endpoint (when in device mode) by reading the device descriptor.
* Normally this reduces the amount of configuration required for the library, allows the value to change dynamically (if
* descriptors are stored in EEPROM or RAM rather than flash memory) and reduces code maintenance. However, this token can be
* defined to a non-zero value instead to give the size in bytes of the control endpoint, to reduce the size of the compiled
* binary.

* <b>DEVICE_STATE_AS_GPIOR</b> - ( \ref Group_Device ) \n
* <b>DEVICE_STATE_AS_GPIOR</b> - (\ref Group_Device) - <i>AVR8 Only</i> \n
* One of the most frequently used global variables in the stack is the USB_DeviceState global, which indicates the current state of
* the Device State Machine. To reduce the amount of code and time required to access and modify this global in an application, this token
* may be defined to a value between 0 and 2 to fix the state variable into one of the three general purpose IO registers inside the AVR
* reserved for application use. When defined, the corresponding GPIOR register should not be used within the user application except
* implicitly via the library APIs.
*
* <b>FIXED_NUM_CONFIGURATIONS</b>=<i>x</i> - ( \ref Group_Device ) \n
* <b>FIXED_NUM_CONFIGURATIONS</b>=<i>x</i> - (\ref Group_Device) - <i>All Architectures</i> \n
* By default, the library determines the number of configurations a USB device supports by reading the device descriptor. This reduces
* the amount of configuration required to set up the library, and allows the value to change dynamically (if descriptors are stored in
* EEPROM or RAM rather than flash memory) and reduces code maintenance. However, this value may be fixed via this token in the project
* makefile to reduce the compiled size of the binary at the expense of flexibility.
*
* <b>CONTROL_ONLY_DEVICE</b> \n
* <b>CONTROL_ONLY_DEVICE</b> - (\ref Group_Device) - <i>All Architectures</i> \n
* In some limited USB device applications, there are no device endpoints other than the control endpoint; i.e. all device communication
* is through control endpoint requests. Defining this token will remove several features related to the selection and control of device
* endpoints internally, saving space. Generally, this is usually only useful in (some) bootloaders and is best avoided.
*
* <b>INTERRUPT_CONTROL_ENDPOINT</b> - ( \ref Group_USBManagement ) \n
* <b>INTERRUPT_CONTROL_ENDPOINT</b> - (\ref Group_USBManagement) - <i>AVR8 Only</i> \n
* Some applications prefer to not call the USB_USBTask() management task regularly 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. When defined, USB_USBTask() does not need to be called
* when in USB device mode.
*
* <b>NO_DEVICE_REMOTE_WAKEUP</b> - (\ref Group_Device ) \n
* <b>NO_DEVICE_REMOTE_WAKEUP</b> - (\ref Group_Device) - <i>All Architectures</i> \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.
