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