+What is anchor?
+===============
+
+A USB driver needs to support some callbacks requiring
+a driver to cease all IO to an interface. To do so, a
+driver has to keep track of the URBs it has submitted
+to know they've all completed or to call usb_kill_urb
+for them. The anchor is a data structure takes care of
+keeping track of URBs and provides methods to deal with
+multiple URBs.
+
+Allocation and Initialisation
+=============================
+
+There's no API to allocate an anchor. It is simply declared
+as struct usb_anchor. init_usb_anchor() must be called to
+initialise the data structure.
+
+Deallocation
+============
+
+Once it has no more URBs associated with it, the anchor can be
+freed with normal memory management operations.
+
+Association and disassociation of URBs with anchors
+===================================================
+
+An association of URBs to an anchor is made by an explicit
+call to usb_anchor_urb(). The association is maintained until
+an URB is finished by (successfull) completion. Thus disassociation
+is automatic. A function is provided to forcibly finish (kill)
+all URBs associated with an anchor.
+Furthermore, disassociation can be made with usb_unanchor_urb()
+
+Operations on multitudes of URBs
+================================
+
+usb_kill_anchored_urbs()
+------------------------
+
+This function kills all URBs associated with an anchor. The URBs
+are called in the reverse temporal order they were submitted.
+This way no data can be reordered.
+
+usb_wait_anchor_empty_timeout()
+-------------------------------
+
+This function waits for all URBs associated with an anchor to finish
+or a timeout, whichever comes first. Its return value will tell you
+whether the timeout was reached.

+What callbacks will usbcore do?
+===============================
+
+Usbcore will call into a driver through callbacks defined in the driver
+structure and through the completion handler of URBs a driver submits.
+Only the former are in the scope of this document. These two kinds of
+callbacks are completely independent of each other. Information on the
+completion callback can be found in Documentation/usb/URB.txt.
+
+The callbacks defined in the driver structure are:
+
+1. Hotplugging callbacks:
+
+ * @probe: Called to see if the driver is willing to manage a particular
+ * interface on a device.
+ * @disconnect: Called when the interface is no longer accessible, usually
+ * because its device has been (or is being) disconnected or the
+ * driver module is being unloaded.
+
+2. Odd backdoor through usbfs:
+
+ * @ioctl: Used for drivers that want to talk to userspace through
+ * the "usbfs" filesystem. This lets devices provide ways to
+ * expose information to user space regardless of where they
+ * do (or don't) show up otherwise in the filesystem.
+
+3. Power management (PM) callbacks:
+
+ * @suspend: Called when the device is going to be suspended.
+ * @resume: Called when the device is being resumed.
+ * @reset_resume: Called when the suspended device has been reset instead
+ * of being resumed.
+
+4. Device level operations:
+
+ * @pre_reset: Called when the device is about to be reset.
+ * @post_reset: Called after the device has been reset
+
+The ioctl interface (2) should be used only if you have a very good
+reason. Sysfs is preferred these days. The PM callbacks are covered
+separately in Documentation/usb/power-management.txt.
+
+Calling conventions
+===================
+
+All callbacks are mutually exclusive. There's no need for locking
+against other USB callbacks. All callbacks are called from a task
+context. You may sleep. However, it is important that all sleeps have a
+small fixed upper limit in time. In particular you must not call out to
+user space and await results.
+
+Hotplugging callbacks
+=====================
+
+These callbacks are intended to associate and disassociate a driver with
+an interface. A driver's bond to an interface is exclusive.
+
+The probe() callback
+--------------------
+
+int (*probe) (struct usb_interface *intf,
+ const struct usb_device_id *id);
+
+Accept or decline an interface. If you accept the device return 0,
+otherwise -ENODEV or -ENXIO. Other error codes should be used only if a
+genuine error occurred during initialisation which prevented a driver
+from accepting a device that would else have been accepted.
+You are strongly encouraged to use usbcore'sfacility,
+usb_set_intfdata(), to associate a data structure with an interface, so
+that you know which internal state and identity you associate with a
+particular interface. The device will not be suspended and you may do IO
+to the interface you are called for and endpoint 0 of the device. Device
+initialisation that doesn't take too long is a good idea here.
+
+The disconnect() callback
+-------------------------
+
+void (*disconnect) (struct usb_interface *intf);
+
+This callback is a signal to break any connection with an interface.
+You are not allowed any IO to a device after returning from this
+callback. You also may not do any other operation that may interfere
+with another driver bound the interface, eg. a power management
+operation.
+If you are called due to a physical disconnection, all your URBs will be
+killed by usbcore. Note that in this case disconnect will be called some
+time after the physical disconnection. Thus your driver must be prepared
+to deal with failing IO even prior to the callback.
+
+Device level callbacks
+======================
+
+pre_reset
+---------
+
+int (*pre_reset)(struct usb_interface *intf);
+
+Another driver or user space is triggering a reset on the device which
+contains the interface passed as an argument. Cease IO and save any
+device state you need to restore.
+
+If you need to allocate memory here, use GFP_NOIO or GFP_ATOMIC, if you
+are in atomic context.
+
+post_reset
+----------
+
+int (*post_reset)(struct usb_interface *intf);
+
+The reset has completed. Restore any saved device state and begin
+using the device again.
+
+If you need to allocate memory here, use GFP_NOIO or GFP_ATOMIC, if you
+are in atomic context.
+
+Call sequences
+==============
+
+No callbacks other than probe will be invoked for an interface
+that isn't bound to your driver.
+
+Probe will never be called for an interface bound to a driver.
+Hence following a successful probe, disconnect will be called
+before there is another probe for the same interface.
+
+Once your driver is bound to an interface, disconnect can be
+called at any time except in between pre_reset and post_reset.
+pre_reset is always followed by post_reset, even if the reset
+failed or the device has been unplugged.
+
+suspend is always followed by one of: resume, reset_resume, or
+disconnect.

* Special thanks to Intel and VIA for providing host controllers to
* test this driver on, and Cypress (including In-System Design) for
* providing early devices for those host controllers to talk to!
- *
- * HISTORY:
- *
- * 2004-05-10 Root hub and PCI suspend/resume support; remote wakeup. (db)
- * 2004-02-24 Replace pci_* with generic dma_* API calls (dsaxena@plexity.net)
- * 2003-12-29 Rewritten high speed iso transfer support (by Michal Sojka,
- * <sojkam@centrum.cz>, updates by DB).
- *
- * 2002-11-29 Correct handling for hw async_next register.
- * 2002-08-06 Handling for bulk and interrupt transfers is mostly shared;
- * only scheduling is different, no arbitrary limitations.
- * 2002-07-25 Sanity check PCI reads, mostly for better cardbus support,
- * clean up HC run state handshaking.
- * 2002-05-24 Preliminary FS/LS interrupts, using scheduling shortcuts
- * 2002-05-11 Clear TT errors for FS/LS ctrl/bulk. Fill in some other
- * missing pieces: enabling 64bit dma, handoff from BIOS/SMM.
- * 2002-05-07 Some error path cleanups to report better errors; wmb();
- * use non-CVS version id; better iso bandwidth claim.
- * 2002-04-19 Control/bulk/interrupt submit no longer uses giveback() on
- * errors in submit path. Bugfixes to interrupt scheduling/processing.
- * 2002-03-05 Initial high-speed ISO support; reduce ITD memory; shift
- * more checking to generic hcd framework (db). Make it work with
- * Philips EHCI; reduce PCI traffic; shorten IRQ path (Rory Bolt).
- * 2002-01-14 Minor cleanup; version synch.
- * 2002-01-08 Fix roothub handoff of FS/LS to companion controllers.
- * 2002-01-04 Control/Bulk queuing behaves.
- *
- * 2001-12-12 Initial patch version for Linux 2.5.1 kernel.
- * 2001-June Works with usb-storage and NEC EHCI on 2.4
