qemu-doc: Update to use the new way of attaching USB devices

Browse source 
The preferred way of adding USB devices is via "-device" and
"device_add" nowadays, so let's start to get rid of "-usbdevice"
and "usb_add" in the documentation. While we're at it, also
add the new USB devices there which have been added to QEMU
during the last years, and get rid of the old "vendorid" and
"productid" parameters of "-usbdevice serial" which have been
removed in QEMU version 0.14.0 already.

* -usbdevice serial::chardev becomes -device usb-serial,chardev=dev.
* -usbdevice braille doesn't support LEGACY-CHARDEV syntax. It always
uses "braille". With -device, this useful default is gone, so you
have to use something like

-chardev braille,id=braille
-device usb-braille,chardev=braille -chardev braille,id=braille

@item usb-mouse
Virtual Mouse. This will override the PS/2 mouse emulation when activated.
@item tablet
@item usb-tablet
Pointer device that uses absolute coordinates (like a touchscreen).
This means QEMU is able to report the mouse position without having
to grab the mouse. Also overrides the PS/2 mouse emulation when activated.
@item disk:@var{file}
Mass storage device based on @var{file} (@pxref{disk_images})

that is presented to the guest.

@item usb-host,vendorid=@var{vendor},productid=@var{product}
Pass through the host device identified by @var{vendor} and @var{product} ID
@item usb-wacom-tablet
Virtual Wacom PenPartner tablet. This device is similar to the @code{tablet}
above but it can be used with the tslib library because in addition to touch
coordinates it reports touch pressure.
@item keyboard
@item usb-kbd
Standard USB keyboard. Will override the PS/2 keyboard (if present).
@item serial:[vendorid=@var{vendor_id}][,product_id=@var{product_id}]:@var{dev}
@item usb-serial,chardev=@var{id}
Serial converter. This emulates an FTDI FT232BM chip connected to host character
device @var{dev}. The available character devices are the same as for the
@code{-serial} option. The @code{vendorid} and @code{productid} options can be
used to override the default 0403:6001. For instance,
@example
usb_add serial:productid=FA00:tcp:192.168.0.2:4444
@end example
will connect to tcp port 4444 of ip 192.168.0.2, and plug that to the virtual
serial converter, faking a Matrix Orbital LCD Display (USB ID 0403:FA00).
@item braille

@item usb-braille,chardev=@var{id}
Braille device. This will use BrlAPI to display the braille output on a real

specifies NIC options as with @code{-net nic,}@var{options} (see description).

@item usb-net[,netdev=@var{id}]
Network adapter that supports CDC ethernet and RNDIS protocols. @var{id}
specifies a netdev defined with @code{-netdev @dots{},id=@var{id}}.
For instance, user-mode networking can be used with
@example
qemu-system-i386 [...OPTIONS...] -net user,vlan=0 -usbdevice net:vlan=0
qemu-system-i386 [...] -netdev user,id=net0 -device usb-net,netdev=net0

Currently this cannot be used in machines that support PCI NICs.
@item bt[:@var{hci-type}]

@item usb-ccid
Smartcard reader device
@item usb-audio
USB audio device
@item usb-bt-dongle
Bluetooth dongle for the transport layer of HCI. It is connected to HCI
scatternet 0 by default (corresponds to @code{-bt hci,vlan=0}).
Note that the syntax for the @code{-device usb-bt-dongle} option is not as
useful yet as it was with the legacy @code{-usbdevice} option. So to
configure an USB bluetooth device, you might need to use
"@code{-usbdevice bt}[:@var{hci-type}]" instead. This configures a
bluetooth dongle whose type is specified in the same format as with
the @option{-bt hci} option, @pxref{bt-hcis,,allowed HCI types}. If
no type is given, the HCI logic corresponds to @code{-bt hci,vlan=0}.
This USB device implements the USB Transport Layer of HCI. Example
