Maybe a bit "perverted" idea, but: Given that the "guest OS"
is more often something like Windows, maybe VirtualBox will
be better in forwarding the USB as-is? Then you will need a
DOS "USB serial port" driver to access your serial devices,
but at least VirtualBox does not have to simulate some type
of device/port out of some other type of device/port? Your
DOS driver would do the transform "inside guest space" :-)
