  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
