The EHCI Host Controller emulation attempt to locate the device
associated with a periodic isochronous transfer description (iTD) and
when this fail the host controller is reset.
But according the EHCI spec 1.0 section 5.15.2.4 Host System
Error, the host controller is supposed to reset itself only when it
failed to communicate with the Host (Operating System), like when
there's an error on the PCI bus. If a transaction fails, there's
nothing in the spec that say to reset the host controller.
This patch rework the error path so that the host controller can keep
working when the OS setup a bogus transaction, it also revert to the
behavior of the EHCI emulation to before commits:
e94682f1fe ("ehci: check device is not NULL before calling usb_ep_get()")
7011baece2 ("usb: remove unnecessary NULL device check from usb_ep_get()")
The issue has been found while trying to passthrough a USB device to a
Windows Server 2012 Xen guest via "usb-ehci", which prevent the USB
device from working in Windows. ("usb-ehci" alone works, windows only
setup this weird periodic iTD to device 127 endpoint 15 when the USB
device is passthrough.)

qemu_hexdump()'s pointer to the buffer and length of the
buffer are closely related arguments but are widely separated
in the argument list order (also, the format of <stdio.h>

Reorder the arguments as "fp, prefix, buf, size" which is

This patch adds the U2F key emulated mode.
The emulated mode consists of completely emulating the behavior of a
U2F device through software part. Libu2f-emu is used for that.
The emulated mode is associated with a device inheriting from
u2f-key base.
To work, an emulated U2F device must have differents elements which
can be given in different ways. This is detailed in docs/u2f.txt.
The Ephemeral one is the simplest way to configure, it lets the device
generate all the elements it needs for a single use of the lifetime
of the device:
qemu -usb -device u2f-emulated

This patch adds the U2F key pass-through mode.
The pass-through mode consists of passing all requests made from the
guest to the physical security key connected to the host machine and
vice versa.
In addition, the dedicated pass-through allows to have a U2F security key
shared on several guests which is not possible with a simple host device
assignment pass-through.
The pass-through mode is associated with a device inheriting from
u2f-key base.
To work, it needs the path to a U2F hidraw, obtained from the Qemu
command line, and passed by the user:
qemu -usb -device u2f-passthru,hidraw=/dev/hidrawX
Autoscan and U2F compatibility checking features are given at the end

On the other hand, it provides the public API used by its variants to

Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path. In particular the tracing headers are using
$(build_root)/$(<D).
In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".
This patch is too ugly to be applied to the Makefiles now. It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.
