I think USB passthorugh works in VirtualBox on macOS so maybe you could 
check how that works there and what might need to be done for it. Although 
I'm not sure if it's in the open source part or in the non-free extensions 
so may not be that easy to find out what's needed if the sources for it 
are not available.
