* @bInterfaceClass: Class of interface; numbers are assigned

* They will then export it to userspace using MODULE_DEVICE_TABLE(),
|

* and provide it to the USB core through their usb_driver structure.
|
||||
*
|
||||
* See the usb_match_id() function for information about how matches are
|
||||
* performed. Briefly, you will normally use one of several macros to help
|
||||
* construct these entries. Each entry you provide will either identify
|
||||
* one or more specific products, or will identify a class of products
|
||||
* which have agreed to behave the same. You should put the more specific
|
||||
* matches towards the beginning of your table, so that driver_info can
|
||||
* record quirks of specific products.
