Add device @var{driver}. Depending on the device type,

@var{option} (typically @var{key}=@var{value}) may be useful.

@var{option} (with default or given @var{value}) may be useful.

To get a help on possible @var{driver}s, @var{option}s or @var{value}s, use

@code{-device ?},

@code{-device @var{driver},?} or

@code{-device @var{driver},@var{option}=?}.
