First time I need this unit and it won't work. Freaking out. Everything connects fine, then the USB just disconnects and reconnects. Then I get about 30 or 40 seconds and it repeats. I NEED THIS WORKING GUYS. 1000's of miles away from home travelling and paid a lot for this tech and have a problem. Changing the USB cable di not solve anything. Reloading drivers did not fix problem. HELP!!!!!
