/**
 * struct usb_device_id - identifies USB devices for probing and hotplugging
 * @match_flags: Bit mask controlling of the other fields are used to match
 *      against new devices.  Any field except for driver_info may be used,
 *      although some only make sense in conjunction with other fields.
 *      This is usually set by a USB_DEVICE_*() macro, which sets all
 *      other fields in this structure except for driver_info.
 * @idVendor: USB vendor ID for a device; numbers are assigned
 *      by the USB forum to its members.
 * @idProduct: Vendor-assigned product ID.
 * @bcdDevice_lo: Low end of range of vendor-assigned product version numbers.
 *      This is also used to identify individual product versions, for
 *      a range consisting of a single device.
 * @bcdDevice_hi: High end of version number range.  The range of product
 *      versions is inclusive.
 * @bDeviceClass: Class of device; numbers are assigned
 *      by the USB forum.  Products may choose to implement classes,
 *      or be vendor-specific.  Device classes specify behavior of all
 *      the interfaces on a devices.
 * @bDeviceSubClass: Subclass of device; associated with bDeviceClass.
 * @bDeviceProtocol: Protocol of device; associated with bDeviceClass.
 * @bInterfaceClass: Class of interface; numbers are assigned
 *      by the USB forum.  Products may choose to implement classes,
 *      or be vendor-specific.  Interface classes specify behavior only
 *      of a given interface; other interfaces may support other classes.
 * @bInterfaceSubClass: Subclass of interface; associated with bInterfaceClass.
 * @bInterfaceProtocol: Protocol of interface; associated with bInterfaceClass.
 * @driver_info: Holds information used by the driver.  Usually it holds
 *      a pointer to a descriptor understood by the driver, or perhaps
 *      device flags.
 *
 * In most cases, drivers will create a table of device IDs by using
 * USB_DEVICE(), or similar macros designed for that purpose.
 * 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.
