Yes, I blame Garmin, USB 3.0 is here to stay and going into all high end laptops and desktops, so if you're behind the times, that's your problem and it appears if i stick with Garmin, mine as well. so much for keeping up with technology.
For anyone still following this, Garmin has not fixed this. YES THIS IS GARMIN's PROBLEM - The Nav V & VI are both not compatible with any USB 3.0 port hubs
GARMIN----- FIX [email protected]!!! you should be embarrassed by now!!!
