  54  * struct usb_device_id - identifies USB devices for probing and hotplugging
  55  * @match_flags: Bit mask controlling of the other fields are used to match
  56  *      against new devices.  Any field except for driver_info may be used,
  57  *      although some only make sense in conjunction with other fields.
  58  *      This is usually set by a USB_DEVICE_*() macro, which sets all
  59  *      other fields in this structure except for driver_info.
  60  * @idVendor: USB vendor ID for a device; numbers are assigned
  61  *      by the USB forum to its members.
  62  * @idProduct: Vendor-assigned product ID.
  63  * @bcdDevice_lo: Low end of range of vendor-assigned product version numbers.
  64  *      This is also used to identify individual product versions, for
  65  *      a range consisting of a single device.
  66  * @bcdDevice_hi: High end of version number range.  The range of product
  67  *      versions is inclusive.
  68  * @bDeviceClass: Class of device; numbers are assigned
  69  *      by the USB forum.  Products may choose to implement classes,
  70  *      or be vendor-specific.  Device classes specify behavior of all
  71  *      the interfaces on a devices.
  72  * @bDeviceSubClass: Subclass of device; associated with bDeviceClass.
  73  * @bDeviceProtocol: Protocol of device; associated with bDeviceClass.
  74  * @bInterfaceClass: Class of interface; numbers are assigned
  75  *      by the USB forum.  Products may choose to implement classes,
  76  *      or be vendor-specific.  Interface classes specify behavior only
  77  *      of a given interface; other interfaces may support other classes.
  78  * @bInterfaceSubClass: Subclass of interface; associated with bInterfaceClass.
  79  * @bInterfaceProtocol: Protocol of interface; associated with bInterfaceClass.
  80  * @driver_info: Holds information used by the driver.  Usually it holds
  81  *      a pointer to a descriptor understood by the driver, or perhaps
  82  *      device flags.
  83  *
  84  * In most cases, drivers will create a table of device IDs by using
  85  * USB_DEVICE(), or similar macros designed for that purpose.
  86  * They will then export it to userspace using MODULE_DEVICE_TABLE(),
  87  * and provide it to the USB core through their usb_driver structure.
  88  *
  89  * See the usb_match_id() function for information about how matches are
  90  * performed.  Briefly, you will normally use one of several macros to help
  91  * construct these entries.  Each entry you provide will either identify
  92  * one or more specific products, or will identify a class of products
  93  * which have agreed to behave the same.  You should put the more specific
  94  * matches towards the beginning of your table, so that driver_info can
  95  * record quirks of specific products.
