/**
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.
