+/**
+ * usb_match_id - find first usb_device_id matching device or interface
+ * @interface: the interface of interest
+ * @id: array of usb_device_id structures, terminated by zero entry
+ *
+ * usb_match_id searches an array of usb_device_id's and returns
+ * the first one matching the device or interface, or null.
+ * This is used when binding (or rebinding) a driver to an interface.
+ * Most USB device drivers will use this indirectly, through the usb core,
+ * but some layered driver frameworks use it directly.
+ * These device tables are exported with MODULE_DEVICE_TABLE, through
+ * modutils, to support the driver loading functionality of USB hotplugging.
+ *
+ * What Matches:
+ *
+ * The "match_flags" element in a usb_device_id controls which
+ * members are used.  If the corresponding bit is set, the
+ * value in the device_id must match its corresponding member
+ * in the device or interface descriptor, or else the device_id
+ * does not match.
+ *
+ * "driver_info" is normally used only by device drivers,
+ * but you can create a wildcard "matches anything" usb_device_id
+ * as a driver's "modules.usbmap" entry if you provide an id with
+ * only a nonzero "driver_info" field.  If you do this, the USB device
+ * driver's probe() routine should use additional intelligence to
+ * decide whether to bind to the specified interface.
+ *
+ * What Makes Good usb_device_id Tables:
+ *
+ * The match algorithm is very simple, so that intelligence in
+ * driver selection must come from smart driver id records.
+ * Unless you have good reasons to use another selection policy,
+ * provide match elements only in related groups, and order match
+ * specifiers from specific to general.  Use the macros provided
+ * for that purpose if you can.
+ *
+ * The most specific match specifiers use device descriptor
+ * data.  These are commonly used with product-specific matches;
+ * the USB_DEVICE macro lets you provide vendor and product IDs,
+ * and you can also match against ranges of product revisions.
+ * These are widely used for devices with application or vendor
+ * specific bDeviceClass values.
+ *
+ * Matches based on device class/subclass/protocol specifications
+ * are slightly more general; use the USB_DEVICE_INFO macro, or
+ * its siblings.  These are used with single-function devices
+ * where bDeviceClass doesn't specify that each interface has
+ * its own class.
+ *
+ * Matches based on interface class/subclass/protocol are the
+ * most general; they let drivers bind to any interface on a
+ * multiple-function device.  Use the USB_INTERFACE_INFO
+ * macro, or its siblings, to match class-per-interface style
+ * devices (as recorded in bDeviceClass).
+ *
+ * Within those groups, remember that not all combinations are
+ * meaningful.  For example, don't give a product version range
+ * without vendor and product IDs; or specify a protocol without
+ * its associated class and subclass.

- * usb_match_id - find first usb_device_id matching device or interface
- * @interface: the interface of interest
- * @id: array of usb_device_id structures, terminated by zero entry
- *
- * usb_match_id searches an array of usb_device_id's and returns
- * the first one matching the device or interface, or null.
- * This is used when binding (or rebinding) a driver to an interface.
- * Most USB device drivers will use this indirectly, through the usb core,
- * but some layered driver frameworks use it directly.
- * These device tables are exported with MODULE_DEVICE_TABLE, through
- * modutils and "modules.usbmap", to support the driver loading
- * functionality of USB hotplugging.
- *
- * What Matches:
- *
- * The "match_flags" element in a usb_device_id controls which
- * members are used.  If the corresponding bit is set, the
- * value in the device_id must match its corresponding member
- * in the device or interface descriptor, or else the device_id
- * does not match.
- *
- * "driver_info" is normally used only by device drivers,
- * but you can create a wildcard "matches anything" usb_device_id
- * as a driver's "modules.usbmap" entry if you provide an id with
- * only a nonzero "driver_info" field.  If you do this, the USB device
- * driver's probe() routine should use additional intelligence to
- * decide whether to bind to the specified interface.
- * 
- * What Makes Good usb_device_id Tables:
- *
- * The match algorithm is very simple, so that intelligence in
- * driver selection must come from smart driver id records.
- * Unless you have good reasons to use another selection policy,
- * provide match elements only in related groups, and order match
- * specifiers from specific to general.  Use the macros provided
- * for that purpose if you can.
- *
- * The most specific match specifiers use device descriptor
- * data.  These are commonly used with product-specific matches;
- * the USB_DEVICE macro lets you provide vendor and product IDs,
- * and you can also match against ranges of product revisions.
- * These are widely used for devices with application or vendor
- * specific bDeviceClass values.
- *
- * Matches based on device class/subclass/protocol specifications
- * are slightly more general; use the USB_DEVICE_INFO macro, or
- * its siblings.  These are used with single-function devices
- * where bDeviceClass doesn't specify that each interface has
- * its own class. 
- *
- * Matches based on interface class/subclass/protocol are the
- * most general; they let drivers bind to any interface on a
- * multiple-function device.  Use the USB_INTERFACE_INFO
- * macro, or its siblings, to match class-per-interface style 
- * devices (as recorded in bDeviceClass).
- *  
- * Within those groups, remember that not all combinations are
- * meaningful.  For example, don't give a product version range
- * without vendor and product IDs; or specify a protocol without
- * its associated class and subclass.

 /*                      USB device locking
  *
- * Although locking USB devices should be straightforward, it is
- * complicated by the way the driver-model core works.  When a new USB
- * driver is registered or unregistered, the core will automatically
- * probe or disconnect all matching interfaces on all USB devices while
- * holding the USB subsystem writelock.  There's no good way for us to
- * tell which devices will be used or to lock them beforehand; our only
- * option is to effectively lock all the USB devices.
- *
- * We do that by using a private rw-semaphore, usb_all_devices_rwsem.
- * When locking an individual device you must first acquire the rwsem's
- * readlock.  When a driver is registered or unregistered the writelock
- * must be held.  These actions are encapsulated in the subroutines
- * below, so all a driver needs to do is call usb_lock_device() and
- * usb_unlock_device().
+ * USB devices and interfaces are locked using the semaphore in their
+ * embedded struct device.  The hub driver guarantees that whenever a
+ * device is connected or disconnected, drivers are called with the
+ * USB device locked as well as their particular interface.
  *
  * Complications arise when several devices are to be locked at the same
  * time.  Only hub-aware drivers that are part of usbcore ever have to
- * do this; nobody else needs to worry about it.  The problem is that
- * usb_lock_device() must not be called to lock a second device since it
- * would acquire the rwsem's readlock reentrantly, leading to deadlock if
- * another thread was waiting for the writelock.  The solution is simple:
- *
- *      When locking more than one device, call usb_lock_device()
- *      to lock the first one.  Lock the others by calling
- *      down(&udev->serialize) directly.
- *
- *      When unlocking multiple devices, use up(&udev->serialize)
- *      to unlock all but the last one.  Unlock the last one by
- *      calling usb_unlock_device().
+ * do this; nobody else needs to worry about it.  The rule for locking
+ * is simple:
  *
  *      When locking both a device and its parent, always lock the
  *      the parent first.

+ *
+ * The 'Alauda' is a chip manufacturered by RATOC for OEM use.
