I feel your pain, I got one of these too. I don't have all those problems but I do get the usb problem. Its the nature of the screen, I added a on/off/ign switch to my setup so that i don't need to pull over to reset things.
Did yours have a cover on the touch screen you needed to take off? I think mine has one but i don't want to pick at it if its just part of the screen.
