/** @page pg_dev_vusb VUSB - Virtual USB
*
* @todo read thru this and correct typos. Merge with old docs.
*
*
* The Virtual USB component glues USB devices and host controllers together.
* The VUSB takes the form of a PDM driver which is attached to the HCI. USB
* devices are created by, attached to, and managed by the VUSB roothub. The
* VUSB also exposes an interface which is used by Main to attach and detach
* proxied USB devices.
*
*
* @section sec_dev_vusb_urb The Life of an URB
*
* The URB is created when the HCI calls the roothub (VUSB) method pfnNewUrb.
* VUSB has a pool of URBs, if no free URBs are availabe a new one is
* allocated. The returned URB starts life in the ALLOCATED state and all
* fields are initalized with sensible defaults.
*
* The HCI then copies any request data into the URB if it's an host2dev
* transfer. It then submits the URB by calling the pfnSubmitUrb roothub
* method.
*
* pfnSubmitUrb will start by checking if it knows the device address, and if
* it doesn't the URB is completed with a device-not-ready error. When the
* device address is known to it, action is taken based on the kind of
* transfer it is. There are four kinds of transfers: 1. control, 2. bulk,
* 3. interrupt, and 4. isochronous. In either case something eventually ends
* up being submitted to the device.
*
*
* If an URB fails submitting, may or may not be completed. This depends on
* heuristics in some cases and on the kind of failure in others. If
* pfnSubmitUrb returns a failure, the HCI should retry submitting it at a
* later time. If pfnSubmitUrb returns success the URB is submitted, and it
* can even been completed.
*
* The URB is in the IN_FLIGHT state from the time it's successfully submitted
* and till it's reaped or cancelled.
*
* When an URB transfer or in some case submit failure occurs, the pfnXferError
* callback of the HCI is consulted about what to do. If pfnXferError indicates
* that the URB should be retried, pfnSubmitUrb will fail. If it indicates that
* it should fail, the URB will be completed.
*
* Completing an URB means that the URB status is set and the HCI
* pfnXferCompletion callback is invoked with the URB. The HCI is the supposed
* to report the transfer status to the guest OS. After completion the URB
* is freed and returned to the pool, unless it was cancelled. If it was
* cancelled it will have to await reaping before it's actually freed.
*
*
* @subsection subsec_dev_vusb_urb_ctrl Control
*
* The control transfer is the most complex one, from VUSB's point of view,
* with its three stages and being bi-directional. A control transfer starts
* with a SETUP packet containing the request description and two basic
* parameters. It is followed by zero or more DATA packets which either picks
* up incoming data (dev2host) or supplies the request data (host2dev). This
* can then be followed by a STATUS packet which gets the status of the whole
* transfer.
*
* What makes the control transfer complicated is that for a host2dev request
* the URB is assembled from the SETUP and DATA stage, and for a dev2host
* request the returned data must be kept around for the DATA stage. For both
* transfer directions the status of the transfer has to be kept around for
* the STATUS stage.
*
* To complicate matters futher, VUSB must intercept and in some cases emulate
* some of the standard requests in order to keep the virtual device state
* correct and provide the correct virtualization of a device.
*
* @subsection subsec_dev_vusb_urb_bulk Bulk and Interrupt
*
* The bulk and interrupt transfer types are relativly simple compared to the
* control transfer. VUSB is not inspecting the request content or anything,
* but passes it down the device.
*
* @subsection subsec_dev_vusb_urb_bulk Isochronous
*
* This kind of transfers hasn't yet been implemented.
*

/** @page pg_dev_vusb_old VUSB - Virtual USB Core
*
* The virtual USB core is controlled by the roothub and the underlying HCI
* emulator, it is responsible for device addressing, managing configurations,
* interfaces and endpoints, assembling and splitting multi-part control
* messages and in general acts as a middle layer between the USB device
* emulation code and USB HCI emulation code.
*
* All USB devices are represented by a struct vusb_dev. This structure
* contains things like the device state, device address, all the configuration
* descriptors, the currently selected configuration and a mapping between
* endpoint addresses and endpoint descriptors.
*
* Each vusb_dev also has a pointer to a vusb_dev_ops structure which serves as
* the virtual method table and includes a virtual constructor and destructor.
* After a vusb_dev is created it may be attached to a hub device such as a
* roothub (using vusbHubAttach). Although each hub structure has cPorts
* and cDevices fields, it is the responsibility of the hub device to allocate
* a free port for the new device.
*
* Devices can chose one of two interfaces for dealing with requests, the
* synchronous interface or the asynchronous interface. The synchronous
* interface is much simpler and ought to be used for devices which are
* unlikely to sleep for long periods in order to serve requests. The
* asynchronous interface on the other hand is more difficult to use but is
* useful for the USB proxy or if one were to write a mass storage device
* emulator. Currently the synchronous interface only supports control and bulk
* endpoints and is no longer used by anything.
*
* In order to use the asynchronous interface, the queue_urb, cancel_urb and
* pfnUrbReap fields must be set in the devices vusb_dev_ops structure. The
* queue_urb method is used to submit a request to a device without blocking,
* it returns 1 if successful and 0 on any kind of failure. A successfully
* queued URB is completed when the pfnUrbReap method returns it. Each function
* address is reference counted so that pfnUrbReap will only be called if there
* are URBs outstanding. For a roothub to reap an URB from any one of it's
* devices, the vusbRhReapAsyncUrbs() function is used.
*
* There are four types of messages an URB may contain:
* -# Control - represents a single packet of a multi-packet control
* transfer, these are only really used by the host controller to
* submit the parts to the usb core.
* -# Message - the usb core assembles multiple control transfers in
* to single message transfers. In this case the data buffer
* contains the setup packet in little endian followed by the full
* buffer. In the case of an host-to-device control message, the
* message packet is created when the STATUS transfer is seen. In
* the case of device-to-host messages, the message packet is
* created after the SETUP transfer is seen. Also, certain control
* requests never go the real device and get handled synchronously.
* -# Bulk - Currently the only endpoint type that does error checking
* and endpoint halting.
* -# Interrupt - The only non-periodic type supported.
*
* Hubs are special cases of devices, they have a number of downstream ports
* that other devices can be attached to and removed from.
*
* After a device has been attached (vusbHubAttach):
* -# The hub attach method is called, which sends a hub status
* change message to the OS.
* -# The OS resets the device, and it appears on the default
* address with it's config 0 selected (a pseudo-config that
* contains only 1 interface with 1 endpoint - the default
* message pipe).
* -# The OS assigns the device a new address and selects an
* appropriate config.
* -# The device is ready.
*
* After a device has been detached (vusbDevDetach):
* -# All pending URBs are cancelled.
* -# The devices address is unassigned.
* -# The hub detach method is called which signals the OS
* of the status change.
* -# The OS unlinks the ED's for that device.
*
* A device can also request detachment from within its own methods by
* calling vusbDevUnplugged().
*
* Roothubs are responsible for driving the whole system, they are special
* cases of hubs and as such implement attach and detach methods, each one
* is described by a struct vusb_roothub. Once a roothub has submitted an
* URB to the USB core, a number of callbacks to the roothub are required
* for when the URB completes, since the roothub typically wants to inform
* the OS when transfers are completed.
*
* There are four callbacks to be concerned with:
* -# prepare - This is called after the URB is successfully queued.
* -# completion - This is called after the URB completed.
* -# error - This is called if the URB errored, some systems have
* automatic resubmission of failed requests, so this callback
* should keep track of the error count and return 1 if the count
* is above the number of allowed resubmissions.
* -# halt_ep - This is called after errors on bulk pipes in order
* to halt the pipe.
