  19 /* Lists of quirky USB devices, split in device quirks and interface quirks.
  20  * Device quirks are applied at the very beginning of the enumeration process,
  21  * right after reading the device descriptor. They can thus only match on device
  22  * information.
  23  *
  24  * Interface quirks are applied after reading all the configuration descriptors.
  25  * They can match on both device and interface information.
  26  *
  27  * Note that the DELAY_INIT and HONOR_BNUMINTERFACES quirks do not make sense as
  28  * interface quirks, as they only influence the enumeration process which is run
  29  * before processing the interface quirks.
  30  *
  31  * Please keep the lists ordered by:
  32  *      1) Vendor ID
  33  *      2) Product ID
  34  *      3) Class ID
