Laurent Pinchart80da2e02012-07-19 12:39:13 +020014/* Lists of quirky USB devices, split in device quirks and interface quirks.
15 * Device quirks are applied at the very beginning of the enumeration process,
16 * right after reading the device descriptor. They can thus only match on device
17 * information.
18 *
19 * Interface quirks are applied after reading all the configuration descriptors.
20 * They can match on both device and interface information.
21 *
22 * Note that the DELAY_INIT and HONOR_BNUMINTERFACES quirks do not make sense as
23 * interface quirks, as they only influence the enumeration process which is run
24 * before processing the interface quirks.
25 *
26 * Please keep the lists ordered by:
Oliver Neukum7ceec1f2007-01-26 14:26:21 +010027 * 1) Vendor ID
28 * 2) Product ID
29 * 3) Class ID
