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