+ *  Still Image Class Driver module. This module contains an internal implementation of the USB Still Image Class,\r
+ *  for USB Host mode only. User applications can use this class driver instead of implementing the Still Image class\r
+ *  manually via the low-level LUFA APIs.\r
+ *\r
+ *  This module is designed to simplify the user code by exposing only the required interface needed to interface with\r
+ *  Devices using the USB Still Image Class.\r
