/* 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
