Last time I tried to remove -usbdevice, there was some concerns that 
-usbdevice braille might still be useful for some people, see the thread 
that started here:

  https://lists.nongnu.org/archive/html/qemu-devel/2018-01/msg00651.html

(and Gerd's summary here: 
https://lists.nongnu.org/archive/html/qemu-devel/2018-01/msg01520.html )

So we might need a new "sugared" option like "-braille" instead before we 
can fully remove -usbdevice? ... or we just keep -usbdevice as a bittersweet 
remainder?
