I have run into this, but within Hyper-V 2010 and used a 3rd party IP addressable USB socket to plug the license dongle into. Then pointed the “guest” to use that IP address as it’s USB port. Been working for years.

For this to work does a user absolutely, positively _have_ to be logged on using an Enhanced Session Mode VM connection? I need to have a piece of software connect to a USB licensing dongle, and it would be, shall we say, less than optimal to have to have user logged in 24/7 and an appropriate VM connection window open. I've got to be missing something, right? If not, MS's solution is useful for one-off stuff, but not for anything where a USB device needs to be connected all the time. I have used USB over network solutions with good success before, so we can certainly go that route. I was just hoping we wouldn't have to.
