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. | |
