43 * Device table entry for "new style" table-driven USB drivers.
44 * User mode code can read these tables to choose which modules to load.
45 * Declare the table as a MODULE_DEVICE_TABLE.
47 * A probe() parameter will point to a matching entry from this table.
48 * Use the driver_info field for each match to hold information tied
49 * to that match: device quirks, etc.
51 * Terminate the driver's table with an all-zeroes entry.
52 * Use the flag values to control which fields are compared.
56 * struct usb_device_id - identifies USB devices for probing and hotplugging
57 * @match_flags: Bit mask controlling which of the other fields are used to
58 * match against new devices. Any field except for driver_info may be
59 * used, although some only make sense in conjunction with other fields.
60 * This is usually set by a USB_DEVICE_*() macro, which sets all
61 * other fields in this structure except for driver_info.
62 * @idVendor: USB vendor ID for a device; numbers are assigned
63 * by the USB forum to its members.
64 * @idProduct: Vendor-assigned product ID.
65 * @bcdDevice_lo: Low end of range of vendor-assigned product version numbers.
66 * This is also used to identify individual product versions, for
67 * a range consisting of a single device.
68 * @bcdDevice_hi: High end of version number range. The range of product
69 * versions is inclusive.
70 * @bDeviceClass: Class of device; numbers are assigned
71 * by the USB forum. Products may choose to implement classes,
72 * or be vendor-specific. Device classes specify behavior of all
73 * the interfaces on a device.
74 * @bDeviceSubClass: Subclass of device; associated with bDeviceClass.
75 * @bDeviceProtocol: Protocol of device; associated with bDeviceClass.
76 * @bInterfaceClass: Class of interface; numbers are assigned
77 * by the USB forum. Products may choose to implement classes,
78 * or be vendor-specific. Interface classes specify behavior only
79 * of a given interface; other interfaces may support other classes.
80 * @bInterfaceSubClass: Subclass of interface; associated with bInterfaceClass.
81 * @bInterfaceProtocol: Protocol of interface; associated with bInterfaceClass.
82 * @bInterfaceNumber: Number of interface; composite devices may use
83 * fixed interface numbers to differentiate between vendor-specific
85 * @driver_info: Holds information used by the driver. Usually it holds
86 * a pointer to a descriptor understood by the driver, or perhaps
89 * In most cases, drivers will create a table of device IDs by using
90 * USB_DEVICE(), or similar macros designed for that purpose.
91 * They will then export it to userspace using MODULE_DEVICE_TABLE(),
92 * and provide it to the USB core through their usb_driver structure.
94 * See the usb_match_id() function for information about how matches are
95 * performed. Briefly, you will normally use one of several macros to help
96 * construct these entries. Each entry you provide will either identify
97 * one or more specific products, or will identify a class of products
98 * which have agreed to behave the same. You should put the more specific
99 * matches towards the beginning of your table, so that driver_info can
100 * record quirks of specific products.
