- *  Define this token to enable the processing of FEATURE HID report items, if any, into the processed HID structure.

+ *  <b>HID_MAX_REPORT_IDS</b> - ( \ref Group_HIDParser ) \n
+ *  HID reports may contain several report IDs, to logically distinguish grouped device data from one another - for example, a combination
+ *  keyboard and mouse might use report IDs to seperate the keyboard reports from the mouse reports. In order to determine the size of each

  *  This section describes compile tokens which affect USB driver stack as a whole in the LUFA library.
  *
  *  <b>USE_RAM_DESCRIPTORS</b> - ( \ref Group_Descriptors ) \n
- *  Define this token to indicate to the USB driver that device descriptors are stored in RAM, rather than the default of

- *  The USB 2.0 standard gives some rather obscure names for the elements in the standard descriptor types (device, configuration,
