| 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. |
