Using spicec, it doesn't give me an option to connection devices. I assume 
usb-redirection for devices *not* on the same machine as the running VM? If 
so, that use case I wasn't testing originally (although useful)

I consider the issue resolved solely on usb-host issue vs any regressions with 
usb-redirection itself which I never used/tried.

However, if someone can point out how you can test this, I can do this also.
