* 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.

* <b>NO_SOF_EVENTS</b> - ( \ref Group_Events ) \n
* By default, there exists a LUFA application event for the start of each USB frame while the USB bus is not suspended in either host or device mode.
* This event can be selectively enabled or disabled by calling the appropriate device or host mode function. When this compile time token is defined,
* the ability to receive USB Start of Frame events via the \ref EVENT_USB_Device_StartOfFrame() or \ref EVENT_USB_Host_StartOfFrame() events is removed,
* reducing the compiled program's binary size.
*
* \section Sec_SummaryUSBDeviceTokens USB Device Mode Driver Related Tokens
* This section describes compile tokens which affect USB driver stack of the LUFA library when used in Device mode.
