  In the hid parser, if a INPUT/OUTPUT/FEATURE item is skipped, its
  corresponding USAGE should be skipped as well.
  
  For example, below is a report desc fragment of some mouse:
  
  COLLECTION
  ...
  USAGE TWHEEL
  FEATURE ...
  ...
  USAGE WHEEL
  INPUT ...
  ...
  END COLLECTION
  
  "USAGE TWHEEL" should be consumed after the FEATURE item is skipped,
  otherwise, the INPUT item will be assigned to "USAGE TWHEEL" later,
  other than "USAGE WHEEL".
