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