   *  <b>Fixed:</b>
   *  - Core:
   *   - Fixed Low Speed USB devices broken when using the library HID Class driver (thanks to Michael)
+  *   - Fixed possible register corruption in USB Host mode on AVR8 devices when ORDERED_EP_CONFIG is used (thanks to Martin Aakerberg)
   *  - Library Applications:
   *   - Added handler for SCSI_CMD_START_STOP_UNIT in demos using the Mass Storage class, to prevent ejection errors on *nix systems due to an
   *     unknown SCSI command
