OK, this is going to sound crazy, but ... I did exactly like you note above - and the same thing happens. My USB device isn't seen / avaiable on start, but after I reset the VM .. voila! It's there and works.
OK, wondering what else it could be. I have a USB hub where the device is plugged in - will try removing that (variable) ... nope, that's not it either. Arrgh!?!? LOL. This really is very odd. I'm open to any thoughts you have.
