- * does not exist on these chips (thanks to Marco)
- * - Changed all Device mode LowLevel demos and Device Class drivers so that the control request is acknowledged and any data
- * transferred as quickly as possible without any processing in between sections, so that long callbacks or event handlers will
- * not break communications with the host by exceeding the maximum control request stage timeout period
