20	*
21	* @todo read thru this and correct typos. Merge with old docs.
22	*
23	*
24	* The Virtual USB component glues USB devices and host controllers together.
25	* The VUSB takes the form of a PDM driver which is attached to the HCI. USB
26	* devices are created by, attached to, and managed by the VUSB roothub. The
27	* VUSB also exposes an interface which is used by Main to attach and detach
28	* proxied USB devices.
29	*
30	*
31	* @section sec_dev_vusb_urb The Life of an URB
32	*
33	* The URB is created when the HCI calls the roothub (VUSB) method pfnNewUrb.
34	* VUSB has a pool of URBs, if no free URBs are available a new one is
35	* allocated. The returned URB starts life in the ALLOCATED state and all
36	* fields are initialized with sensible defaults.
37	*
38	* The HCI then copies any request data into the URB if it's an host2dev
39	* transfer. It then submits the URB by calling the pfnSubmitUrb roothub
40	* method.
41	*
42	* pfnSubmitUrb will start by checking if it knows the device address, and if
43	* it doesn't the URB is completed with a device-not-ready error. When the
44	* device address is known to it, action is taken based on the kind of
45	* transfer it is. There are four kinds of transfers: 1. control, 2. bulk,
46	* 3. interrupt, and 4. isochronous. In either case something eventually ends
47	* up being submitted to the device.
48	*
49	*
50	* If an URB fails submitting, may or may not be completed. This depends on
51	* heuristics in some cases and on the kind of failure in others. If
52	* pfnSubmitUrb returns a failure, the HCI should retry submitting it at a
53	* later time. If pfnSubmitUrb returns success the URB is submitted, and it
54	* can even been completed.
55	*
56	* The URB is in the IN_FLIGHT state from the time it's successfully submitted
57	* and till it's reaped or cancelled.
58	*
59	* When an URB transfer or in some case submit failure occurs, the pfnXferError
60	* callback of the HCI is consulted about what to do. If pfnXferError indicates
61	* that the URB should be retried, pfnSubmitUrb will fail. If it indicates that
62	* it should fail, the URB will be completed.
63	*
64	* Completing an URB means that the URB status is set and the HCI
65	* pfnXferCompletion callback is invoked with the URB. The HCI is the supposed
66	* to report the transfer status to the guest OS. After completion the URB
67	* is freed and returned to the pool, unless it was cancelled. If it was
68	* cancelled it will have to await reaping before it's actually freed.
69	*
70	*
71	* @subsection subsec_dev_vusb_urb_ctrl Control
72	*
73	* The control transfer is the most complex one, from VUSB's point of view,
74	* with its three stages and being bi-directional. A control transfer starts
75	* with a SETUP packet containing the request description and two basic
76	* parameters. It is followed by zero or more DATA packets which either picks
77	* up incoming data (dev2host) or supplies the request data (host2dev). This
78	* can then be followed by a STATUS packet which gets the status of the whole
79	* transfer.
80	*
81	* What makes the control transfer complicated is that for a host2dev request
82	* the URB is assembled from the SETUP and DATA stage, and for a dev2host
83	* request the returned data must be kept around for the DATA stage. For both
84	* transfer directions the status of the transfer has to be kept around for
85	* the STATUS stage.
86	*
87	* To complicate matters further, VUSB must intercept and in some cases emulate
88	* some of the standard requests in order to keep the virtual device state
89	* correct and provide the correct virtualization of a device.
90	*
91	* @subsection subsec_dev_vusb_urb_bulk Bulk and Interrupt
92	*
93	* The bulk and interrupt transfer types are relativly simple compared to the
94	* control transfer. VUSB is not inspecting the request content or anything,
95	* but passes it down the device.
96	*
97	* @subsection subsec_dev_vusb_urb_bulk Isochronous
98	*
99	* This kind of transfers hasn't yet been implemented.

104	/** @page pg_dev_vusb_old VUSB - Virtual USB Core
105	*
106	* The virtual USB core is controlled by the roothub and the underlying HCI
107	* emulator, it is responsible for device addressing, managing configurations,
108	* interfaces and endpoints, assembling and splitting multi-part control
109	* messages and in general acts as a middle layer between the USB device
110	* emulation code and USB HCI emulation code.
111	*
112	* All USB devices are represented by a struct vusb_dev. This structure
113	* contains things like the device state, device address, all the configuration
114	* descriptors, the currently selected configuration and a mapping between
115	* endpoint addresses and endpoint descriptors.
116	*
117	* Each vusb_dev also has a pointer to a vusb_dev_ops structure which serves as
118	* the virtual method table and includes a virtual constructor and destructor.
119	* After a vusb_dev is created it may be attached to a hub device such as a
120	* roothub (using vusbHubAttach). Although each hub structure has cPorts
121	* and cDevices fields, it is the responsibility of the hub device to allocate
122	* a free port for the new device.
123	*
124	* Devices can chose one of two interfaces for dealing with requests, the
125	* synchronous interface or the asynchronous interface. The synchronous
126	* interface is much simpler and ought to be used for devices which are
127	* unlikely to sleep for long periods in order to serve requests. The
128	* asynchronous interface on the other hand is more difficult to use but is
129	* useful for the USB proxy or if one were to write a mass storage device
130	* emulator. Currently the synchronous interface only supports control and bulk
131	* endpoints and is no longer used by anything.
132	*
133	* In order to use the asynchronous interface, the queue_urb, cancel_urb and
134	* pfnUrbReap fields must be set in the devices vusb_dev_ops structure. The
135	* queue_urb method is used to submit a request to a device without blocking,
136	* it returns 1 if successful and 0 on any kind of failure. A successfully
137	* queued URB is completed when the pfnUrbReap method returns it. Each function
138	* address is reference counted so that pfnUrbReap will only be called if there
139	* are URBs outstanding. For a roothub to reap an URB from any one of it's
140	* devices, the vusbRhReapAsyncUrbs() function is used.
141	*
142	* There are four types of messages an URB may contain:
143	* -# Control - represents a single packet of a multi-packet control
144	* transfer, these are only really used by the host controller to
145	* submit the parts to the usb core.
146	* -# Message - the usb core assembles multiple control transfers in
147	* to single message transfers. In this case the data buffer
148	* contains the setup packet in little endian followed by the full
149	* buffer. In the case of an host-to-device control message, the
150	* message packet is created when the STATUS transfer is seen. In
151	* the case of device-to-host messages, the message packet is
152	* created after the SETUP transfer is seen. Also, certain control
153	* requests never go the real device and get handled synchronously.
154	* -# Bulk - Currently the only endpoint type that does error checking
155	* and endpoint halting.
156	* -# Interrupt - The only non-periodic type supported.
157	*
158	* Hubs are special cases of devices, they have a number of downstream ports
159	* that other devices can be attached to and removed from.
160	*
161	* After a device has been attached (vusbHubAttach):
162	* -# The hub attach method is called, which sends a hub status
163	* change message to the OS.
164	* -# The OS resets the device, and it appears on the default
165	* address with it's config 0 selected (a pseudo-config that
166	* contains only 1 interface with 1 endpoint - the default
167	* message pipe).
168	* -# The OS assigns the device a new address and selects an
169	* appropriate config.
170	* -# The device is ready.
171	*
172	* After a device has been detached (vusbDevDetach):
173	* -# All pending URBs are cancelled.
174	* -# The devices address is unassigned.
175	* -# The hub detach method is called which signals the OS
176	* of the status change.
177	* -# The OS unlinks the ED's for that device.
178	*
179	* A device can also request detachment from within its own methods by
180	* calling vusbDevUnplugged().
181	*
182	* Roothubs are responsible for driving the whole system, they are special
183	* cases of hubs and as such implement attach and detach methods, each one
184	* is described by a struct vusb_roothub. Once a roothub has submitted an
185	* URB to the USB core, a number of callbacks to the roothub are required
186	* for when the URB completes, since the roothub typically wants to inform
187	* the OS when transfers are completed.
188	*
189	* There are four callbacks to be concerned with:
190	* -# prepare - This is called after the URB is successfully queued.
191	* -# completion - This is called after the URB completed.
192	* -# error - This is called if the URB errored, some systems have
193	* automatic resubmission of failed requests, so this callback
194	* should keep track of the error count and return 1 if the count
195	* is above the number of allowed resubmissions.
196	* -# halt_ep - This is called after errors on bulk pipes in order
197	* to halt the pipe.
