  17. * Device quirks are applied at the very beginning of the enumeration process,

  19. * information.
  20. *
  21. * Interface quirks are applied after reading all the configuration descriptors.
  22. * They can match on both device and interface information.
  23. *
  24. * Note that the DELAY_INIT and HONOR_BNUMINTERFACES quirks do not make sense as
  25. * interface quirks, as they only influence the enumeration process which is run
  26. * before processing the interface quirks.

  30. * 2) Product ID
