  usb-ccid: convert CCIDCardClass::exitfn() -> unrealize()
  usb-ccid: inline ccid_card_initfn() in ccid_card_realize()
  hw/usb/ccid: Make ccid_card_init() take an error parameter
  usb-storage: Fix share-rw option parsing
  usb: Remove legacy -usbdevice options (host, serial, disk and net)

@item disk:[format=@var{format}]:@var{file}
Mass storage device based on file. The optional @var{format} argument
will be used rather than detecting the format. Can be used to specify
@code{format=raw} to avoid interpreting an untrusted format header.
@item host:@var{bus}.@var{addr}
Pass through the host device identified by @var{bus}.@var{addr} (Linux only).
@item host:@var{vendor_id}:@var{product_id}
Pass through the host device identified by @var{vendor_id}:@var{product_id}
(Linux only).
@item serial:[vendorid=@var{vendor_id}][,productid=@var{product_id}]:@var{dev}
Serial converter to host character device @var{dev}, see @code{-serial} for the
available devices.
@item braille
Braille device. This will use BrlAPI to display the braille output on a real
or fake device.
@item net:@var{options}
