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
