To use as a companion controller, use pci-ohci as device and set the
masterbus and num-ports properties, ie:
-device usb-ehci,addr=0b.1,multifunction=on,id=ehci0
-device pci-ohci,addr=0b.0,multifunction=on,masterbus=ehci0.0,num-ports=4

with the "usb-ehci: cleanup port reset handling" patch in place no callers
are calling usb_attach(port, NULL) for a port where port->dev is NULL.
Doing that makes no sense as that causes the port detach op to get called
for a port with nothing attached. Add an assert that port->dev != NULL when
dev == NULL, and remove the check for not having a port->dev in the dev == NULL
case.

Doing a usb_attach when dev is NULL will just result in the

Note this fixes 2 things in one go, first of all the device_destroy bus
op should be a device_detach bus op, as pending async packets from the
device should be cancelled on detach not on destroy.
Secondly having this as a bus op won't work with companion controllers, since
then there will be 1 bus driven by the ehci controller and thus 1 set of bus
ops, but the device being detached may be downstream of a handed over port.
Making the detach of a downstream device a port op allows the ehci controller
to forward this to the companion controller port for handed over ports.

This makes them consistent with the attach and detach ops, and in general
it makes sense to make portops take a port as argument. This also makes
adding support for a companion controller easier / cleaner.

In musb_packet() handle final processing of non-asynchronous
USB packets by directly calling musb_schedule_cb() rather than
going through usb_packet_complete(). The latter will trigger
an assertion because the packet doesn't belong to a device.

-device virtserialport,chardev=foo,name=org.qemu.guest_agent
I get a segfault when booting a Fedora 14 guest. The backtrace says:
Program terminated with signal 11, Segmentation fault.

335 info = DO_UPCAST(VirtIOSerialPortInfo, qdev, port->dev.info);
What's happening is VIRTIO_CONSOLE_DEVICE_READY is a message for the
whole device, not for an individual port. So port is NULL. This bug was
introduced by commit a15bb0d6a9.
This commit fixes that by making the port returned by find_port_by_id()
be used only by the VIRTIO_CONSOLE_PORT_READY and
VIRTIO_CONSOLE_PORT_OPEN messages.

* when the controller is suspended but the port is not, raise RD
* when the controller is suspended, move it to resume state

This is used to indicate at which speed[s] the device can operate,
so that this can be checked to match the ports capabilities when it gets
attached to a bus.
Note that currently all usb1 emulated device claim to be fullspeed, this
seems to not cause any problems, but still seems wrong, because with real
hardware keyboards, mice and tablets usually are lo-speed, so reporting these
as fullspeed devices seems wrong.

Add properties for the wakeup rate and the max number of frames ehci
will process at once.
The wakeup rate defaults to 1000 which equals the usb frame rate. This
can be reduced to make qemu wake up less often when ehci is active.
In case the wakeup rate is reduced or the ehci timer is delayed due to
latency issues elsewhere in qemu ehci will process multiple frames at
once. The maxframes property specifies the upper limit for this.
