+ * these transitions quiesce the driver, so that I/O queues are inactive.
+ * That commonly entails turning off IRQs and DMA; there may be rules
+ * about how to quiesce that are specific to the bus or the device's type.
+ * (For example, network drivers mark the link state.)  Other details may
+ * differ according to the message:
+ *
+ * SUSPEND	Quiesce, enter a low power device state appropriate for
+ * 		the upcoming system state (such as PCI_D3hot), and enable
+ * 		wakeup events as appropriate.
+ *
+ * HIBERNATE	Enter a low power device state appropriate for the hibernation
+ * 		state (eg. ACPI S4) and enable wakeup events as appropriate.
+ *
+ * FREEZE	Quiesce operations so that a consistent image can be saved;
+ * 		but do NOT otherwise enter a low power device state, and do
+ * 		NOT emit system wakeup events.
+ *
+ * PRETHAW	Quiesce as if for FREEZE; additionally, prepare for restoring
+ * 		the system from a snapshot taken after an earlier FREEZE.
+ * 		Some drivers will need to reset their hardware state instead
+ * 		of preserving it, to ensure that it's never mistaken for the
+ * 		state which that earlier snapshot had set up.
+ *
+ * A minimally power-aware driver treats all messages as SUSPEND, fully
+ * reinitializes its device during resume() -- whether or not it was reset
+ * during the suspend/resume cycle -- and can't issue wakeup events.
+ *
+ * More power-aware drivers may also use low power states at runtime as
+ * well as during system sleep states like PM_SUSPEND_STANDBY.  They may

+ * The driver that is bound to the interface can use standard driver model
+ * calls such as dev_get_drvdata() on the dev member of this structure.
+ *
+ * Each interface may have alternate settings.  The initial configuration
+ * of a device sets altsetting 0, but the device driver can change
+ * that setting using usb_set_interface().  Alternate settings are often
+ * used to control the use of periodic endpoints, such as by having
+ * different endpoints use different amounts of reserved USB bandwidth.
+ * All standards-conformant USB devices that use isochronous endpoints
+ * will use them in non-default settings.
+ *
+ * The USB specification says that alternate setting numbers must run from
+ * 0 to one less than the total number of alternate settings.  But some
+ * devices manage to mess this up, and the structures aren't necessarily
+ * stored in numerical order anyhow.  Use usb_altnum_to_altsetting() to

+
+/**
+ * struct urb - USB Request Block
+ * @urb_list: For use by current owner of the URB.
+ * @anchor_list: membership in the list of an anchor
+ * @anchor: to anchor URBs to a common mooring
+ * @ep: Points to the endpoint's data structure.  Will eventually
+ *	replace @pipe.
+ * @pipe: Holds endpoint number, direction, type, and more.
+ *	Create these values with the eight macros available;
+ *	usb_{snd,rcv}TYPEpipe(dev,endpoint), where the TYPE is "ctrl"
+ *	(control), "bulk", "int" (interrupt), or "iso" (isochronous).
+ *	For example usb_sndbulkpipe() or usb_rcvintpipe().  Endpoint
+ *	numbers range from zero to fifteen.  Note that "in" endpoint two
+ *	is a different endpoint (and pipe) from "out" endpoint two.
+ *	The current configuration controls the existence, type, and
+ *	maximum packet size of any given endpoint.
+ * @dev: Identifies the USB device to perform the request.
+ * @status: This is read in non-iso completion functions to get the
+ *	status of the particular request.  ISO requests only use it
+ *	to tell whether the URB was unlinked; detailed status for
+ *	each frame is in the fields of the iso_frame-desc.
+ * @transfer_flags: A variety of flags may be used to affect how URB
+ *	submission, unlinking, or operation are handled.  Different
+ *	kinds of URB can use different flags.
+ * @transfer_buffer:  This identifies the buffer to (or from) which
+ * 	the I/O request will be performed (unless URB_NO_TRANSFER_DMA_MAP
+ *	is set).  This buffer must be suitable for DMA; allocate it with
+ *	kmalloc() or equivalent.  For transfers to "in" endpoints, contents
+ *	of this buffer will be modified.  This buffer is used for the data
+ *	stage of control transfers.
+ * @transfer_dma: When transfer_flags includes URB_NO_TRANSFER_DMA_MAP,
+ *	the device driver is saying that it provided this DMA address,
+ *	which the host controller driver should use in preference to the
+ *	transfer_buffer.
+ * @transfer_buffer_length: How big is transfer_buffer.  The transfer may
+ *	be broken up into chunks according to the current maximum packet
+ *	size for the endpoint, which is a function of the configuration
+ *	and is encoded in the pipe.  When the length is zero, neither
+ *	transfer_buffer nor transfer_dma is used.
+ * @actual_length: This is read in non-iso completion functions, and
+ *	it tells how many bytes (out of transfer_buffer_length) were
+ *	transferred.  It will normally be the same as requested, unless
+ *	either an error was reported or a short read was performed.
+ *	The URB_SHORT_NOT_OK transfer flag may be used to make such
+ *	short reads be reported as errors.
+ * @setup_packet: Only used for control transfers, this points to eight bytes
+ *	of setup data.  Control transfers always start by sending this data
+ *	to the device.  Then transfer_buffer is read or written, if needed.
+ * @setup_dma: For control transfers with URB_NO_SETUP_DMA_MAP set, the
+ *	device driver has provided this DMA address for the setup packet.
+ *	The host controller driver should use this in preference to
+ *	setup_packet.
+ * @start_frame: Returns the initial frame for isochronous transfers.
+ * @number_of_packets: Lists the number of ISO transfer buffers.
+ * @interval: Specifies the polling interval for interrupt or isochronous
+ *	transfers.  The units are frames (milliseconds) for for full and low
+ *	speed devices, and microframes (1/8 millisecond) for highspeed ones.
+ * @error_count: Returns the number of ISO transfers that reported errors.
+ * @context: For use in completion functions.  This normally points to
+ *	request-specific driver context.
+ * @complete: Completion handler. This URB is passed as the parameter to the
+ *	completion function.  The completion function may then do what
+ *	it likes with the URB, including resubmitting or freeing it.
+ * @iso_frame_desc: Used to provide arrays of ISO transfer buffers and to
+ *	collect the transfer status for each buffer.
+ *
+ * This structure identifies USB transfer requests.  URBs must be allocated by
+ * calling usb_alloc_urb() and freed with a call to usb_free_urb().
+ * Initialization may be done using various usb_fill_*_urb() functions.  URBs
+ * are submitted using usb_submit_urb(), and pending requests may be canceled
+ * using usb_unlink_urb() or usb_kill_urb().
+ *
+ * Data Transfer Buffers:
+ *
+ * Normally drivers provide I/O buffers allocated with kmalloc() or otherwise
+ * taken from the general page pool.  That is provided by transfer_buffer
+ * (control requests also use setup_packet), and host controller drivers
+ * perform a dma mapping (and unmapping) for each buffer transferred.  Those
+ * mapping operations can be expensive on some platforms (perhaps using a dma
+ * bounce buffer or talking to an IOMMU),
+ * although they're cheap on commodity x86 and ppc hardware.
+ *
+ * Alternatively, drivers may pass the URB_NO_xxx_DMA_MAP transfer flags,
+ * which tell the host controller driver that no such mapping is needed since
+ * the device driver is DMA-aware.  For example, a device driver might
+ * allocate a DMA buffer with usb_buffer_alloc() or call usb_buffer_map().
+ * When these transfer flags are provided, host controller drivers will
+ * attempt to use the dma addresses found in the transfer_dma and/or
+ * setup_dma fields rather than determining a dma address themselves.  (Note
+ * that transfer_buffer and setup_packet must still be set because not all
+ * host controllers use DMA, nor do virtual root hubs).
+ *
+ * Initialization:
+ *
+ * All URBs submitted must initialize the dev, pipe, transfer_flags (may be
+ * zero), and complete fields.  All URBs must also initialize
+ * transfer_buffer and transfer_buffer_length.  They may provide the
+ * URB_SHORT_NOT_OK transfer flag, indicating that short reads are
+ * to be treated as errors; that flag is invalid for write requests.
+ *
+ * Bulk URBs may
+ * use the URB_ZERO_PACKET transfer flag, indicating that bulk OUT transfers
+ * should always terminate with a short packet, even if it means adding an
+ * extra zero length packet.
+ *
+ * Control URBs must provide a setup_packet.  The setup_packet and
+ * transfer_buffer may each be mapped for DMA or not, independently of
+ * the other.  The transfer_flags bits URB_NO_TRANSFER_DMA_MAP and
+ * URB_NO_SETUP_DMA_MAP indicate which buffers have already been mapped.
+ * URB_NO_SETUP_DMA_MAP is ignored for non-control URBs.
+ *
+ * Interrupt URBs must provide an interval, saying how often (in milliseconds
+ * or, for highspeed devices, 125 microsecond units)
+ * to poll for transfers.  After the URB has been submitted, the interval
+ * field reflects how the transfer was actually scheduled.
+ * The polling interval may be more frequent than requested.
+ * For example, some controllers have a maximum interval of 32 milliseconds,
+ * while others support intervals of up to 1024 milliseconds.
+ * Isochronous URBs also have transfer intervals.  (Note that for isochronous
+ * endpoints, as well as high speed interrupt endpoints, the encoding of
+ * the transfer interval in the endpoint descriptor is logarithmic.
+ * Device drivers must convert that value to linear units themselves.)
+ *
+ * Isochronous URBs normally use the URB_ISO_ASAP transfer flag, telling
+ * the host controller to schedule the transfer as soon as bandwidth
+ * utilization allows, and then set start_frame to reflect the actual frame
+ * selected during submission.  Otherwise drivers must specify the start_frame
+ * and handle the case where the transfer can't begin then.  However, drivers
+ * won't know how bandwidth is currently allocated, and while they can
+ * find the current frame using usb_get_current_frame_number () they can't
+ * know the range for that frame number.  (Ranges for frame counter values
+ * are HC-specific, and can go from 256 to 65536 frames from "now".)
+ *
+ * Isochronous URBs have a different data transfer model, in part because
+ * the quality of service is only "best effort".  Callers provide specially
+ * allocated URBs, with number_of_packets worth of iso_frame_desc structures
+ * at the end.  Each such packet is an individual ISO transfer.  Isochronous
+ * URBs are normally queued, submitted by drivers to arrange that
+ * transfers are at least double buffered, and then explicitly resubmitted
+ * in completion handlers, so
+ * that data (such as audio or video) streams at as constant a rate as the
+ * host controller scheduler can support.
+ *
+ * Completion Callbacks:
+ *
+ * The completion callback is made in_interrupt(), and one of the first
+ * things that a completion handler should do is check the status field.
+ * The status field is provided for all URBs.  It is used to report
+ * unlinked URBs, and status for all non-ISO transfers.  It should not
+ * be examined before the URB is returned to the completion handler.
+ *
+ * The context field is normally used to link URBs back to the relevant
+ * driver or request state.
+ *
+ * When the completion callback is invoked for non-isochronous URBs, the
+ * actual_length field tells how many bytes were transferred.  This field
+ * is updated even when the URB terminated with an error or was unlinked.
+ *
+ * ISO transfer status is reported in the status and actual_length fields
+ * of the iso_frame_desc array, and the number of errors is reported in
+ * error_count.  Completion callbacks for ISO transfers will normally
+ * (re)submit URBs to ensure a constant transfer rate.
+ *
+ * Note that even fields marked "public" should not be touched by the driver
+ * when the urb is owned by the hcd, that is, since the call to
+ * usb_submit_urb() till the entry into the completion routine.

+ *	If this interface does not use the USB major, this field should
+ *	be unused.  The driver should set this value in the probe()
+ *	function of the driver, after it has been assigned a minor
+ *	number from the USB core by calling usb_register_dev().
+ * @condition: binding state of the interface: not bound, binding
+ *	(in probe()), bound to a driver, or unbinding (in disconnect())
+ * @sysfs_files_created: sysfs attributes exist
+ * @ep_devs_created: endpoint child pseudo-devices exist
+ * @unregistering: flag set when the interface is being unregistered

+ *	has been deferred.
+ * @needs_binding: flag set when the driver should be re-probed or unbound
+ *	following a reset or suspend operation it doesn't support.
+ * @dev: driver model's view of this device
+ * @usb_dev: if an interface is bound to the USB major, this will point
+ *	to the sysfs representation for that device.
+ * @pm_usage_cnt: PM usage counter for this interface
+ * @reset_ws: Used for scheduling resets from atomic context.
+ * @reset_running: set to 1 if the interface is currently running a
+ *      queued reset so that usb_cancel_queued_reset() doesn't try to
+ *      remove from the workqueue when running inside the worker
+ *      thread. See __usb_queue_reset_device().
+ *
+ * USB device drivers attach to interfaces on a physical device.  Each
+ * interface encapsulates a single high level function, such as feeding
+ * an audio stream to a speaker or reporting a change in a volume control.
+ * Many USB devices only have one interface.  The protocol used to talk to
+ * an interface's endpoints can be defined in a usb "class" specification,
+ * or by a product's vendor.  The (default) control endpoint is part of
+ * every interface, but is never listed among the interface's descriptors.
+ *
+ * The driver that is bound to the interface can use standard driver model
+ * calls such as dev_get_drvdata() on the dev member of this structure.
+ *
+ * Each interface may have alternate settings.  The initial configuration
+ * of a device sets altsetting 0, but the device driver can change
+ * that setting using usb_set_interface().  Alternate settings are often
+ * used to control the use of periodic endpoints, such as by having
+ * different endpoints use different amounts of reserved USB bandwidth.
+ * All standards-conformant USB devices that use isochronous endpoints
+ * will use them in non-default settings.
+ *
+ * The USB specification says that alternate setting numbers must run from
+ * 0 to one less than the total number of alternate settings.  But some
+ * devices manage to mess this up, and the structures aren't necessarily
+ * stored in numerical order anyhow.  Use usb_altnum_to_altsetting() to
+ * look up an alternate setting in the altsetting array based on its number.

+ * @anchor: to anchor URBs to a common mooring
+ * @ep: Points to the endpoint's data structure.  Will eventually
+ *	replace @pipe.
+ * @pipe: Holds endpoint number, direction, type, and more.
+ *	Create these values with the eight macros available;
+ *	usb_{snd,rcv}TYPEpipe(dev,endpoint), where the TYPE is "ctrl"
+ *	(control), "bulk", "int" (interrupt), or "iso" (isochronous).
+ *	For example usb_sndbulkpipe() or usb_rcvintpipe().  Endpoint
+ *	numbers range from zero to fifteen.  Note that "in" endpoint two
+ *	is a different endpoint (and pipe) from "out" endpoint two.
+ *	The current configuration controls the existence, type, and
+ *	maximum packet size of any given endpoint.
+ * @dev: Identifies the USB device to perform the request.
+ * @status: This is read in non-iso completion functions to get the
+ *	status of the particular request.  ISO requests only use it
+ *	to tell whether the URB was unlinked; detailed status for
+ *	each frame is in the fields of the iso_frame-desc.
+ * @transfer_flags: A variety of flags may be used to affect how URB
+ *	submission, unlinking, or operation are handled.  Different
+ *	kinds of URB can use different flags.
+ * @transfer_buffer:  This identifies the buffer to (or from) which
+ * 	the I/O request will be performed (unless URB_NO_TRANSFER_DMA_MAP
+ *	is set).  This buffer must be suitable for DMA; allocate it with
+ *	kmalloc() or equivalent.  For transfers to "in" endpoints, contents
+ *	of this buffer will be modified.  This buffer is used for the data
+ *	stage of control transfers.
+ * @transfer_dma: When transfer_flags includes URB_NO_TRANSFER_DMA_MAP,
+ *	the device driver is saying that it provided this DMA address,
+ *	which the host controller driver should use in preference to the
+ *	transfer_buffer.
+ * @transfer_buffer_length: How big is transfer_buffer.  The transfer may
+ *	be broken up into chunks according to the current maximum packet
+ *	size for the endpoint, which is a function of the configuration
+ *	and is encoded in the pipe.  When the length is zero, neither
+ *	transfer_buffer nor transfer_dma is used.
+ * @actual_length: This is read in non-iso completion functions, and
+ *	it tells how many bytes (out of transfer_buffer_length) were
+ *	transferred.  It will normally be the same as requested, unless
+ *	either an error was reported or a short read was performed.
+ *	The URB_SHORT_NOT_OK transfer flag may be used to make such
+ *	short reads be reported as errors.
+ * @setup_packet: Only used for control transfers, this points to eight bytes
+ *	of setup data.  Control transfers always start by sending this data
+ *	to the device.  Then transfer_buffer is read or written, if needed.
+ * @setup_dma: For control transfers with URB_NO_SETUP_DMA_MAP set, the
+ *	device driver has provided this DMA address for the setup packet.
+ *	The host controller driver should use this in preference to
+ *	setup_packet.
+ * @start_frame: Returns the initial frame for isochronous transfers.
+ * @number_of_packets: Lists the number of ISO transfer buffers.
+ * @interval: Specifies the polling interval for interrupt or isochronous
+ *	transfers.  The units are frames (milliseconds) for for full and low
+ *	speed devices, and microframes (1/8 millisecond) for highspeed ones.
+ * @error_count: Returns the number of ISO transfers that reported errors.
+ * @context: For use in completion functions.  This normally points to
+ *	request-specific driver context.
+ * @complete: Completion handler. This URB is passed as the parameter to the
+ *	completion function.  The completion function may then do what
+ *	it likes with the URB, including resubmitting or freeing it.
+ * @iso_frame_desc: Used to provide arrays of ISO transfer buffers and to
+ *	collect the transfer status for each buffer.
+ *
+ * This structure identifies USB transfer requests.  URBs must be allocated by
+ * calling usb_alloc_urb() and freed with a call to usb_free_urb().
+ * Initialization may be done using various usb_fill_*_urb() functions.  URBs
+ * are submitted using usb_submit_urb(), and pending requests may be canceled
+ * using usb_unlink_urb() or usb_kill_urb().
+ *
+ * Data Transfer Buffers:
+ *
+ * Normally drivers provide I/O buffers allocated with kmalloc() or otherwise
+ * taken from the general page pool.  That is provided by transfer_buffer
+ * (control requests also use setup_packet), and host controller drivers
+ * perform a dma mapping (and unmapping) for each buffer transferred.  Those
+ * mapping operations can be expensive on some platforms (perhaps using a dma
+ * bounce buffer or talking to an IOMMU),
+ * although they're cheap on commodity x86 and ppc hardware.
+ *
+ * Alternatively, drivers may pass the URB_NO_xxx_DMA_MAP transfer flags,
+ * which tell the host controller driver that no such mapping is needed since
+ * the device driver is DMA-aware.  For example, a device driver might
+ * allocate a DMA buffer with usb_alloc_coherent() or call usb_buffer_map().
+ * When these transfer flags are provided, host controller drivers will
+ * attempt to use the dma addresses found in the transfer_dma and/or
+ * setup_dma fields rather than determining a dma address themselves.  (Note
+ * that transfer_buffer and setup_packet must still be set because not all
+ * host controllers use DMA, nor do virtual root hubs).
+ *
+ * Initialization:
+ *
+ * All URBs submitted must initialize the dev, pipe, transfer_flags (may be
+ * zero), and complete fields.  All URBs must also initialize
+ * transfer_buffer and transfer_buffer_length.  They may provide the
+ * URB_SHORT_NOT_OK transfer flag, indicating that short reads are
+ * to be treated as errors; that flag is invalid for write requests.
+ *
+ * Bulk URBs may
+ * use the URB_ZERO_PACKET transfer flag, indicating that bulk OUT transfers
+ * should always terminate with a short packet, even if it means adding an
+ * extra zero length packet.
+ *
+ * Control URBs must provide a setup_packet.  The setup_packet and
+ * transfer_buffer may each be mapped for DMA or not, independently of
+ * the other.  The transfer_flags bits URB_NO_TRANSFER_DMA_MAP and
+ * URB_NO_SETUP_DMA_MAP indicate which buffers have already been mapped.
+ * URB_NO_SETUP_DMA_MAP is ignored for non-control URBs.
+ *
+ * Interrupt URBs must provide an interval, saying how often (in milliseconds
+ * or, for highspeed devices, 125 microsecond units)
+ * to poll for transfers.  After the URB has been submitted, the interval
+ * field reflects how the transfer was actually scheduled.
+ * The polling interval may be more frequent than requested.
+ * For example, some controllers have a maximum interval of 32 milliseconds,
+ * while others support intervals of up to 1024 milliseconds.
+ * Isochronous URBs also have transfer intervals.  (Note that for isochronous
+ * endpoints, as well as high speed interrupt endpoints, the encoding of
+ * the transfer interval in the endpoint descriptor is logarithmic.
+ * Device drivers must convert that value to linear units themselves.)
+ *
+ * Isochronous URBs normally use the URB_ISO_ASAP transfer flag, telling
+ * the host controller to schedule the transfer as soon as bandwidth
+ * utilization allows, and then set start_frame to reflect the actual frame
+ * selected during submission.  Otherwise drivers must specify the start_frame
+ * and handle the case where the transfer can't begin then.  However, drivers
+ * won't know how bandwidth is currently allocated, and while they can
+ * find the current frame using usb_get_current_frame_number () they can't
+ * know the range for that frame number.  (Ranges for frame counter values
+ * are HC-specific, and can go from 256 to 65536 frames from "now".)
+ *
+ * Isochronous URBs have a different data transfer model, in part because
+ * the quality of service is only "best effort".  Callers provide specially
+ * allocated URBs, with number_of_packets worth of iso_frame_desc structures
+ * at the end.  Each such packet is an individual ISO transfer.  Isochronous
+ * URBs are normally queued, submitted by drivers to arrange that
+ * transfers are at least double buffered, and then explicitly resubmitted
+ * in completion handlers, so
+ * that data (such as audio or video) streams at as constant a rate as the
+ * host controller scheduler can support.
+ *
+ * Completion Callbacks:
+ *
+ * The completion callback is made in_interrupt(), and one of the first
+ * things that a completion handler should do is check the status field.
+ * The status field is provided for all URBs.  It is used to report
+ * unlinked URBs, and status for all non-ISO transfers.  It should not
+ * be examined before the URB is returned to the completion handler.
+ *
+ * The context field is normally used to link URBs back to the relevant
+ * driver or request state.
+ *
+ * When the completion callback is invoked for non-isochronous URBs, the
+ * actual_length field tells how many bytes were transferred.  This field
+ * is updated even when the URB terminated with an error or was unlinked.
+ *
+ * ISO transfer status is reported in the status and actual_length fields
+ * of the iso_frame_desc array, and the number of errors is reported in
+ * error_count.  Completion callbacks for ISO transfers will normally
+ * (re)submit URBs to ensure a constant transfer rate.
+ *
+ * Note that even fields marked "public" should not be touched by the driver
+ * when the urb is owned by the hcd, that is, since the call to
+ * usb_submit_urb() till the entry into the completion routine.
