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.
23 * Interface quirks are applied after reading all the configuration descriptors.
24 * They can match on both device and interface information.
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.
30 * Please keep the lists ordered by:
31 * 1) Vendor ID
32 * 2) Product ID
33 * 3) Class ID
